JTAPI and vg224
Anyone know if JTAPI supports call control on the vg224. I know that it works on the vg248 but since the 224 is IOS based, was wondering if there is a difference.
Mark
@gpulos: are you sure about that? The protocols you listed are signalling protocols.. jtapi is a cti protocol.. I'm pretty sure you won't find jtapi mentioned on any phone/device product page .. it's a feature the call manager offers.
I don't have a VG224 device to test, but I added one to my ccm, configured one of the ports, added a line to it, and then I was able to create a device association via my cti user.. so if that's possible, the device should be monitor-able via JTAPI and TAPI.

Hello,
I have been getting mixed responses and would like to know what the actual experts say on JTAPI and the potential "load" it places on CUCM. What I am specifically referring to is FPC (1st party control) and TPC (3rd party control), but more specifically just adding a user then adding devices to be monitored for the lone purpose of getting device presence information. This means no CTI route points or CTI ports actually being used.
Since this means that an actual JTAPI session would need to be open (I am using a simple JTAPI listener to get OnHook/OffHook events), I understand that there will be *some* load, but I cannot see where this would cause a significant increase in resource use on CUCM.
Would someone please share their thoughts on this? Thank you.You can get alot of information as to whats going on in the callcenter via the HDS database. You can also connect into the CTI interface on the CTIOS server. To get information via the ctitoolkit. Remember that JTAPI can way heavily on the CPU load on a server, and the agents add additional overhead to a standard CUCM box as well. You might run into a device weight issue if you get too carried away.

JTAPI and AXL interfering with each other
This has been driving me crazy today.
I had to write a custom callforward app, which upon setting the call forward, modifies some line properties as well (remove any pickup group that may be present).
To set the callforward, I've been using JTAPI and I've had this operation operational for over a year in a productive environment. Now I've added the updateLine axl command, and all of a sudden, the application no longer does what it's supposed to.
Here is what happens: via the phone interface, I enter the number I want to forward to, then send the request to my webserver. There, the forward is set via JTAPI without exceptions being thrown (since setting / removing a cfwd gets no feedback, getting an exception = it didn't work). Then, I send the updateLine for the lines I've just forwarded. It all works out nicely, the apps comes back telling the user all his calls have been forwarded to number X.
However, no callforwarding is actually made even though JTAPI came through telling me everything was okay. However, the pickup group does get removed from the line.
If you then try the same operation again, this time there's only the JTAPI part as the line no longer is in the pickup group, and now the operation works like as reliable as it has always done before.
Writing a sample app is going to be a bitch because this thing isn't quite so simple (and I'm re-using a lot of class libs of other projects so I can't just send the source code of everything to cisco) so I might not open a case on this but I thought I'd let you know.. and if Cisco employees visit this forum maybe they could spare some time trying to replicate.
Now I'm stick having to rewrite the whole callforwarding via axl which technically isn't a problem, but it's just going to take up time that wasn't forseen in this particular project :(In order to modify a package, the developer would need to acquire a lock on the package. So Oracle would prevent two developers from modifying a package simultaneously. It would do nothing, though, to prevent two developers from serially overwriting each other's changes. That's one of the many reasons that you use an external source control system when developing any code, including database packages.

Help needed- Caller tone application using JTAPI and JMF
Hi to All,
I want to make a Caller Tone Application for Cisco IP phone.
For that application I am using JTAPI and JMF.
I am new to this two technologies.
Can somebody help me for how to accomplish this?
---AshishHi Jerry,
You can run analog input and counter tasks concurrently. You can start them using software timing basically at the same time which may be fine for your needs and is the easiest to implement. You also can use a hardware start trigger to start the tasks if you prefer. It all depends on the level of synchronization you need.
You have not mentioned at what rate you will be acquiring data on your analog inputs. The M Series PCI-6225 has 80 analog inputs and may suit your needs. You will need to know what sampling rate you are trying to achieve. Any M Series device will definitely give you the best value.
Hope this helps!

QOS on 1861 and VG224 FXS Interfaces
I will be connecting a couple of 1861's...and also some VG224's to 2821 and 3825 routers. If i am plugging analog phones into the FXS ports on the 1861's and VG224's do they automatically mark the packets coming from the FXS interfaces as voice packets (EF) or do i need to do this manually?...if so i am not sure how i would because the interfaces are voice ports which i havent assigned ip addresses to...I would imagine that if i was using an IP phone instead of analogue i would be able to set the QOS on the phone itself so as to get end to end packet marking, but how does this happen with an analogue phone that has no QOS or IP capabilities?
Thanks and regards,if u have voip dial peer point to ur CCM then u can make the marking through this dial peer
for example
dial-peer voice 1 voip
distination-patren [ccm ip]
codec g711ulaw
no vad
ip qos dscp ef media
ip qos dscp cs3 signaling
however what i sugest u is because u have the VG will be on one vlan which is the vlan that belongs to voice lets say vlan 20
so just creat an ACL that match all traffic coming fron that vlan for example the range will be like 10.1.1.0/24
so make somthing not exactly but similer to :
ip access-list extended call-signaling
permit tcp any any range 1719 1720
permit tcp any any range 2428
ip access-list extended VVLAN
permit udp 10.1.1.0 0.0.0.255 any range 16384 32767
class-map match-all VVLAN-VOICE
match access-group VVLAN
class VVLAN-CALL-SIGNALING
match access-group call-signaling
policy-map VG-marking
class VVLAN-VOICE
set ip dscp 46
class VVLAN-CALL-SIGNALING
set ip dscp 24
here the interface gos from the VG to the lan
interface [port number]
service-policy input VG-marking
u can chose from the above to ways which one suit u
good luck

Hi,
does Cisco provide call center classes with their JTAPI? For instance, i would like to monitor Call center events with the JTAPI application, the same way i can monitor events on Call manager.

Do we need to open specific port to allow JTAPI client outside of corporate firewall to communicate with CUCM?
it depends on where your application server sits.. if it's in the voice zone you shouldn't need any changes, but if not, you definitely need to open ports. The ports needed are mentioned in the JTAPI developer guide (it's a single one.. and another one if you use secure JTAPI). Of course, if you want to do media (cti ports, cti routepoints) then you'll need a whole bunch of ports (the JTAPI port plus whatever ports the phones use.. I don't have the link handy but it's part of the callmanager documentation.. a single PDF that lists all ports the callmanager ever uses, including the JTAPI port).

Hello,
-Are there any Classes from Cisco JTAPI, implementing the javax.telephony.* Interfaces?
_Where can I get the com.cisco.ipphone (for JTAPI 1.4) and com.cisco.jtapi packages?
- Are there better Specifications like the one on :
http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_programming_reference_guide_chapter09186a00801ea3b3.html
Thanx for helpCisco JTAPI does implement much of the javax.telephony series of interfaces. You pick up the actual JTAPI classes and such when you install the JTAPI plugin from CallManager. You go into CCMAdmin, to the Plugins menu, and then pick JTAPI off the list.
You can find some pretty good documentation over in Developer Support:

Hi,
If anyone can please help with the following. (Please let me know if the questions are unclear or ignorantly asked).
I have limited experiance with JTAPI, i have a program that monitors phones in our company and this uses Jtapi (with Avaya's Jtapi implementation) to monitor and make phone calls, which is send to a specific terminal (In this case a physical phone at the user's desk).
Now i want to make a phone call, but not send it to a phone, but play it through the users earphone on the pc using MSTAPI.
Questions:
1. If a phone call is made using openH323, do you require a modem attached to the PC? (preferably we would not want to connect a modem to each persons pc)
2. If we can do it without a modem, what is the call actually connected to (What converts the data into voice format).
I will have more questions, but if someone could help me with these 2 first please, then i will be able to have a better idea of how to ask the other questions.
I have searched the web for 3 days straight now without finding a real solution to my problems.
Thanks in advance.The problem is that they want an inhouse written one, that way we will be able incorporate it into our database and add functionality that is related to our database and current system. (for example, if a client phones a user, and the user does not answer, we can create a reminder to phone back the number if we got the caller id, to phone the client back as soon as he logs onto our main system, with the client's information. We will also be able to create our own reports on the calls that was made, eg clients that falls under a specific category. if this makes sense.

PG JTAPI and CM failure, how to connect with others?
Hi All;
The main site has UCCE side A (RGR-a,PG-a, HDS&ICM&Webview-a), CVP servers and VXML Servers, Gatekeeper, two Voice Gateways and Cluster of CUCM (publisher and 3 subscribers).
Disaster Recovery site has UCCE side B (RGR-a, PG-a, HDS&ICM&Webview-a), CVP Servers and VXML Servers, Gatekeeper, two Voice Gateways and 3 CUCM all subscribers while the publisher in the main site, so the CUCM are clustered with main site.
If the CUCM in the main site had a failure (the publisher and the 3 subscribers), what are the needed configuration need to be done in the main site at the UCCE side A to let it able to communicate with the CUCM subscribers in the Disaster Recovery? Is this failover possible to be autmatic or I have to do it manual?
Your kindly advise is highly appreciated.
Regards
BilalHi Bilal,
one PG can connect to only one CUCM CTI Manager. The redundancy is within the PG A and PG B.
So, if the CTI Manager that the PG A connects fails, PG B JGW process will be become active and will communicate with CTI Manager that PG B connects.
Now, that the connectivity of PG to CTI Manager. But the CTI RP's may register to different Subscriber depending on how the callmanager group is defined on device pool that is assigned to CTI RP.
You should have the Callmanager group for the CTI RP such that it contains both main site and fail over site call managers.
Here are some scenarios.
lets say, you have
sub1 and sub2 on main site
sub3 and sub4 on recovery site
PGA connect to sub1 CTI manager, and PGB connects to sub3 CTI manager. Callmanager group (sub1, sub2, sub3 and sub4 in order) for the CTI RP contains all the call managers
Failure Scenario:
1. If sub2 fails - JGW process on PG B will be active. But CTI RPs will be registered to sub2
2. if sub1 fails, JGW process will reamin active on PG A. but RPs will be registered to sub2
3. if both sub1 and sub2 fails, JGW process will be active on PG B and RPs will be registered on sub3
Hope this helps.
Thanks

Hi
We have developped a simple java application which can read the addres (phone number) of an incoming call on a terminal.
Now we've installed a pilot point which redirects to multiple terminals and we can't read the address anymore (for example: pilot point with number 2233 redirects to terminals with number 9337, 9248, .....). We always get an "unkown" number.
We've used someting like tcev.getCall().getConnections()[1].getAddress().getName(); to get the address (where tcev is TermConnEv). We also looped through all Connections but can't find the callers address.
Tried different ways but found no conclusion...
Any idea?
Many thanks!

If you are monitoring all call and terminal events for all phones via JTAPI, does it burden your CUCM since it has to respond to your app about these events -- specially when you have more than a thousand phone. Are there some guidelines about JTAPI performance and limits -- i.e maximum number of phones/JTAPI client, etc.
Please check you have enabled AXL updates on the Call Manager side:
For CUCM 4.x
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/dir_plugin/plug413.html
Do you have the CTI Manager service running on the server you're attempting to make a JTAPI Provider?
In CRS 4.x and later, it should create the JTAPI and RM JTAPI users, but it may prompt for CCM 'administrator' credentials to add the users. If you have MLA enabled, this really means the 'ccmadministrator' user or a user with similar privileges. -
Change CUCM PIM in Package CCE and JTAPI Client
Hi All,
I have PCCE 10.5 here. In PCCE there is 1 CUCM PIM in PG A and 1 in side B. I want to change CUCM PIM in side B to another CUCM. What's impact if I change ip address of CUCM PIM and then re install JTAPI client? Do I need restarted some services or anything else? Thank you.
BR,
Roythen you can just change the IP address in pim configuration while installing PG.
if the CUCM version subscriber running is different then previous one, re install the JTAPI and restart PG side B service. that should be enough.
Regards

/* This method is invoked when end user cHe, the code is in there twice so it's not as big as it first seems.
Your problem doesn't seem to be programming related however, it's more of a hardware problem. If the code can't get a provider, then you need to figure out why it can't. Maybe there are applications out there that you can use to test if you can get to a provider from your workstation? -
RTP streaming and Cisco IP phones problem
Hello,
I'm trying to write an application that should dial some numbers and play the voice message from the file into the phone line using Cisco JTAPI and Java Media Framework.
I've found some samples, that seems useful for me, but unfortunately they does not work. There are no any errors and no exceptions, I have no idea what to do.
Small brief: I make a call from one Cisco IP phone (7960) to another using Cisco JTAPI, then I catch the CiscoRTPInputStartedEv event, get the IP and port of the IP Phone and call the RTPStreamer class constuctor with them. It gives no any errors or exceptions (just a message shown below), but there is only silence in the phone line. Message:
Should b streamin'...
Encoding ok?: true
streams is [Lcom.sun.media.multiplexer.RawBufferMux$RawBufferSourceStream;@53d : 1
sink: setOutputLocator rtp://192.168.1.22:20794/audio
Please see the RTFStreamer class code below.
I set the packet size to 160 as reccomended for Cisco IP phones, I use the greeting.wav from Cisco example that properties are 8Khz 8bit mono, but it still doesn't work.
Could you help me? Thank you for any advice!
