Outbound SIP calls to invalid numbers

what is the expected behavior for a sip call to an invalid number? and what would cause it to behave differently?

Hi Ronald,
Whats the call flow ex IP Phone --SCCP-> CUCM --SIP --> CUBE -SIP-> Telco
If called number is invalid then call should not ring. Why is far end responding back with ringing.
Can you grab below debugs from the VG
++ debug voice ccapi inout
++ debug ccsip messages
HTH,

CVP Opsconsole: Patterns for RNA timeout on outbound SIP calls - Dialed Number (DN) text box does not take any input

Hi there,
I'm having problems modifying the 'Dialed Number (DN)' text box under 'Advanced Configuration->Patterns for RNA timeout on outbound SIP calls' of the SIP tab in the Cisco Unified Customer Voice Portal 8.5(1) opsconsole. In a nut shell, I need to change the RNA timeout but some reason when typing into the Dialed Number text box, the input is not taken. The reason I want to change this settings is because my ICM Rona is not working with CVP:

Thanks in advance for any help.

Hello Dale,
CVP doesn't allow you to exceed the RNA more than 60 Seconds. If you want to configure the timer for DN Patterns you should do it via OPS console, It would update the sip.properties files in correct way, the above way is incorrect.

Automatic call blocking from invalid numbers/Smart Limits for Wireless changes

It would be nice if your call routing system could be set to AUTOMATICALLY prevent calls from invalid phone numbers from being completed. As an example, I have received calls on my cell phone with the following Caller ID numbers in the last few days: 408-189-xxxx728-727-xxxx The first number uses an invalid exchange (189); the second an inactive area code (728). These were both obviously spoofed numbers that spammers/fraudsters are using. While I get many, many more nuisance calls than these examples each week, it would relieve some of the call volume if your system blocks these calls in the first place. I also subscribe to the Smart Limits call blocking service. 30 numbers is NOT enough to cover all of the spam calls I get. Could this be increased to at least 200? I have already used up all 30 slots in my Smart Limits. I also have over 50 numbers programmed into my phone's phonebook that have been flagged as spammers. Since they can either change the numbers they transmit on a regular basis, or there's just so many of them to begin with, 30 numbers is much too low. Would it also be possible to count and record the date and time when calls have last been blocked and have this information posted with the list of my blocked numbers? It would be useful to see how many times that calls from the number have been received and when the last one was blocked. I could then delete that number from my block list and replace it with one that has had more activity.

Hi there
Thank you for posting your valuable feedback on our Smart Limits service!
As with everything we offer, we rely on this feedback to provide services that our customers find useful, and to make existing products even better. I agree that adding an automatic block for such calls would be an awesome option, ad would being able to increase the blocked contact limit and see records of those blocked calls! There may be some technical limitations preventing us from adding these features at this time, but we will certainly pass your comments on to the teams that can make this happen!
Thanks again!

Call ended - invalid phone number

Skype keeps telling me I am entering an invalid phone number. I have tried several time without success. I have credit in my account that I cannot use. I am talking of a landline in Chile here not even a cell phone.
The message "call ended - invalid phone number" appears every time I try to call a number that I have called regularly for the past year. Don't know why it stopped working or how to remedy it. I have tried dialing from my contacts list as well as dialing directly.
Sometimes (not always) other numbers in the same city seem to work making it a selective issue.
I can't figure out what's wrong.
This matter has been popping up since last year and no one in the bloody company of Skype has been able to supply a proper response in the community area or at least an instruction to fix it for ever more.
If any of these seems familiar to you it's because I cut and paste messages of different people having the same problem although with no solution at hand

I am having the same issue. I have checked for updates, but it says I have the most up-to-date version, I have checked my subscription, no problems there, I even have almost $15 in credit in addition to an unlimited monthly subscription. I think the problem started when Microsoft started messing with Skype. I am going to be asking for a refund on my credit and the past several months of my subscription if this issue can't be resolved. It won't work from either of my laptops, PS3, iPhone or iPad... Thier billing still seems to be working though, they charge me every month even though I can't use the service. I have sent messages to thier support as well but have not heard a word back. Any suggestions? Have already uninstalled and re-installed a few times...

Incoming sip calls are not working but outgoing is working with cme

I have CME setup with voip.ms on my 2800 router, my outgoing calls are working but my incoming calls are not. Below is my config, please let me know if it is something with my config:

I made the change, but I am getting no output from debug voip ccapi inout. What does concern me from debug ccsip messages is:

Rogue SIP calls on C40

Hello,
We have a VC system with public IP address registered to VCS-E receiving various rogue SIP calls. All of these SIP calls are 3 - 6 digit alias lasting for 32 sec each. The incoming call address is: alias@ our VC system's public IP address. All calls are video calls at 384k
To avoid the calls, I have turned off the SIP option and since then we have not received any of these calls. However, we need to connect to other devices using SIP. Is there another way to stop these incoming calls?
Thanks in advance for your help.
Amrit

Set the following on your endpoints:
xConfiguration SIP ListenPort: Off
xConfiguration SIP Profile 1 Outbound: On
See bug CSCue55239 for more details.
You'll also need to take steps to secure your VCS if you haven't already, turning off SIP UDP will stop the SIP calls. However, within the last year we've seen these calls come over H323 TCP, the only way to stop the H323 calls is either secure the endpoint behind your firewall, and use a CPL script on the VCS. See the sourceh323idcisco-incomingcalls discussion on how to setup a CPL.
FYI, searching the forums would be my first place to look, or bug search. It's been asked all over the place in the forums.

SIP to SIP Call Failures on CME to CME - sip-ua conflict/issue?

Hi,
I have two existing CME systems which I wish to allow internal calls between. These calls will go over an IPSec VPN. However the calls are failing.
Phones DN22xx - London CME 2801 - PIX505 --- Internet ---ASA5505 - India CME 2801 - Phones DN400x
I have configured dial peers on both CME's and the IPSec VPN. I can ping between both systems. The VPN allows traffic between the interface IP's of the CME systems only.
London CME (local SCCP phones 22xx):

The CME system at India also has an existing SIP dial peer to a service provider and has sip-ua configured (username, password, realm and registrar).
A call from India (4005) to London (DN2207) fails, the ccsip debug attached. I'm assuming its because the sip-ua configuration is being used for these calls to when I don't want it to be. The from field shows âFrom: <sip:[email protected]â when I need this to be the internal IP 192.168.15.10.
Can anyone offer any assistance with this?
Regards,
Chris

Hi,
thanks for your input however thats not the problem. 201.196.128.56 isn't an address on the router, it only has one IP and its 192.168.15.10.
The 201.196.128.56 address is the NAT'd address on the firewall. So that when a SIP call is made to the internet with sip-ua the from address is the public IP.
Chris

Thanks this was very useful.. I have a brand new iphone 4s unlocked version from singapore and I am having the same problem constant network fluctuations, no service, call failed, invalid sim, sim failure, bars fluctuating from 5 - 3 - 2 - 1, no signal/ba

I have a brand new iphone 4s unlocked version from singapore and I am experiencing constant network fluctuations on my iphone , no service, call failed, invalid sim, sim failure, bars fluctuating from 5 - 3 - 2 - 1, no signal/bars searching etc... Ifeel miserable after trying out all the options changed multiple sims, tried multiple carriers, restored the phone back and have set-up as new device but the problem does not get solved... its is so frustrating that after investing on a world's most expensive phone you cannot enjoy the calling features which the phone offers which is the main thing you own the phone for.. Rest of the things are working.. The funniest part I am not able to make calls or receive calls but can access the internet.. I have tried every possible thing and really very frustrated with this iphone of mine...I hope the problem gets solved.. would anyone have any solutions to this problem.. Does it mean one should never update software as I hear that after updating to IOS.5.1 the problem has started coming and same has been with there.... Apple says its a hardware failure which is very difficult to digest as sometimes I get 5 bars and able to make and receive calls but 95% of the time I am unable to. If anyone has any solution I will be very happy if he or share can share the same. Many thanks. its so disgusting to experience this on top of this apple does not support global warranty for the phone as you need to go to the country from where you bought the phone for replacement.. Truly sad state of affairs.. very very very dissappointing.

Have a look at this it might help

Facing difficulty calling any Indian numbers (mobi...

I am facing difficulty calling any Indian numbers from UAE. I have recently subscribed to Skype calls to India. Everytime I call to any number, the call gets connected and drop after few seconds. Neither side is able hear anything. There is no ring tone either when the connection is made.
I tried with Skype App for Windows 8 and also Skype for Desktop. Same problem with Connection.
It is depressing that I cannot make calls after I have recently purchased subscription for 12months!
Could someone suggest a wayout?
Thanks

Calling Australian mobile numbers

What Skype plans allow me to call australian mobile phones. I will be calling from both Australia and overseas. My old pay asyou go plan seemed to allow this. I recently got a 'premium' plan. It does not appear to allow me to call Australian mobile phones. Please confirm that pay as you go is the only way to call australian mobile phones. If that is the case can you have two plans on one skpe name -say a pay as you go and a 'premium' and have it work so that the 'premium' time would be deducted if possible and the pay as you go would only be consumed if the call could not be made under the 'premium' plan. Otherwise I will just have to have two skype names , one under premium and one under pay as you go.
I must say I find the information on what are the call restrictions on the various plans is not easy to find.

Where does it state it is allowed?
The roaming page says what it cost if you are in Bosnia not if you call a mobile there.On the Calling abroad from the UK page (not roaming page). Scroll down to the "Standard call rates", expand it and see Zone 5.
I've been in similar situation when was unable to place a call to Latvia for a week or so (actually, calls to different numbers in Latvia from different operators). I've been on the phone with EE every day, and noone was able to find out what's wrong (starting from standard "reboot your phone" etc to level 3 tech). Only at the end of the week one of the CSR found out that calls to Latvia were barred acros whole network without any notice/info/reason. Long story short - accepted £61.50 compensation.

IDOC no. for outbound JIT calls

Hi,
I need to extract idoc number for all outbound jit calls that I can view in Outbound JIT call monitor.Can anyone please tell me that which table is used to store the generated idoc no. for a particular call/component group in a call.
Thanks,
Gauri

Hello,
There is one transaction code BDM2 which is the link between the INBOUND IDOC and the OUTBOUND IDOC
I never used this transaction, but try
OR as an alternative
There is a Function module SREL_GET_NEXT_NEIGHBOR
Goto the Transaction code SE37 and give this FM
OBJECT-OBJKEY = <IDoc number, 16-digits>
OBJECT-OBJTYPE = 'IDOC'
MAX_HOPS = '99'
and execute
it will give the Outbound idocs for the inbound idocs
I hope this will solve your requirement.

Blocking calls from Unknown numbers?

Hello all,
Is there any option/application in iPhone 4S, IOS6.1.3 where I can block any calls from unknown numbers?
Specifying exactly, I want to receive calls from people only those whose numbers are saved in my phone or say Saved Contacts Only.
Nobody other than that should be able to call me.
That would be of a great help.

How to calling 1 800 numbers and then input confer...

I know that I can call 1-800 numbers in the USA but I need to be on a conference call via 1-800 number on Monday. Once the 1 800 number is answered, a voice asks me to enter the code to join the conference call. how do I do that as there is no keyboard to enter the numbers? Do I just enter the numbers after the original 1 800 number call? Please advise. Thanks,

Unable to call mobile phone numbers - Play mobile network - Poland

Hi, I'm trying to call some mobile phone numbers in Poland and still got answer: "sorry you can not call this number". 2 or 3 months before it wasn't a problem but now seems that it's related only to one mobile network in Poland - Play. Do you have any idea whether they've changed their policy recently? Thank you in advance.

I just contacted Skype support. The issue has been rosolved!!! The CALLER ID must be set up, otherwise PLAY will not accept the calls! I set up my Caller Id and suddenly was able to call all PLAY numbers! Thank you Skype for your efficient technical support!!! SKYPE RULES!!!!!

ICM 7.5-how to get individual outbound dialer calls talktime and respective ECC values

Hello,
I'm looking for following two items
1. Outbound dialer calls talktime in each call.
2. Each calls respective ECC values.
I have tried to get talktime from TCD table it’s shows zero value.
Please advice how to get above values, it would be much appreciated.
Thanks
Regards,
Param

Hey Param,
You can use the PeripheralCallType in the TCD table to find dialer calls. Look for calls with:
PeripheralCallType IN ('27','28','29','30','31') for reservation calls and
PeripheralCallType IN ('32','33','34','35') for the customer calls
For duration of reservation calls look at the HoldTime value
For duration of the customer call you can look at the HoldTime + TalkTime + WorkTime for a total handle time for the customer leg of the dialer call
If you want to look at the ECC variables that were associated with that call you will have to lookup the Termination_Call_Variable table matching:
Termination_Call_Variable.TCDRecoveryKey = Termination_Call_Detail.RecoveryKey
Cheers,
Nathan
