H.323 MCU 3515 as H.323 Gateway in CCM

Hi,
I have a little bit confusion and i hope u can help me clear it up!!
In which cases the MCU 3115(H.323 enabled) is configured in CCM as a H.323 Gateway??
Plz help me to clear this up, i need help urgently.
Thank you.

Hi Mikheil,
Could u please inform if the call to the originating endpoint is released, before you get the "recovery on timer expiry message"??
Also, the restrictions on Call Redirection Web page requires IVR to be setup for this feature to work. Is this setup?? Could u give more explanation regarding the problem.
thanks and regards,
Amit.

H.323 gateway behind NAT

i configued h.323 gateway (gateway is connected PSTN through FXO) behind internet NAT router and try to call that gateway from a softphone through internet. the dialed PSTN no is ringging but no voice for both ways. Pls refer the attached configuration. Is this a problem with NAT translation?
Thanks in advance!

Yes, you need a version of IOS that has NAT ALG. What IOS are you running?
NAT with ALG can translate the embedded addresses in H225/H245.

Can Call Manager support network side Q.931 from H.323 gateways

With CCM 3.1, is it possible to support network side E1 Q.931 on a H.323 gateway. This would allow PABXs to connect to CCM, which then allow CCM to act as a tandem exchange.

The network side support on the H323 gateway
is transparent to the CCM. They are two seperate call legs.
1. pots for E1 PRI and
2. voip call leg to CCM.
The support for network side PRI is on 2600/3600/3700/7700/AS5300,AS5800
and its been available since 12.1(3)T and please use
a more recent image 12.2T train ip plus at the least.

Help with setting up Caller-id on FXO in 2911 H.323 gateway.

I have a remote site that has a couple of POTS lines terminating to a FXO on the 2911. This remote site is an H.323 gateway in a CUCM 8.6 cluster. Incoming local calls for that location ring all phones at the location.
What do I need to do to enable Caller-id on these POTS lines terminating to the FXO? I am pretty sure the carrier is sending the caller ID information.
Thanks

Hi

MGCP and H.323 gateways not working together

We have a 3640 in Mexico defined to our Call Manager here in Atlanta as a H.323 gateway. Also in the same Call Manager is a T1 PRI defined to our PBX as a MGCP gateway. When people in Mexico call phones connected to our PBX we get one way conversations. We have a couple of other H.323 to MGCP gateways situations that don't work. It seems the two are not compatible. Has anyone else ran into this. If so, what was your solution.

According to your description, I believe that you have a topology like the following diagram.
MexicoPSTN---?---3640---h.323---CCM---mgcp---gateway?---PRI---PBX
You didn't mentioned what type of circuit you had between the 3640 and the telco in Mexico or the type of gateway used for MGCP in Atlanta.
However, there should be no problems with this type of configuration causing one-way audio.
In this case CallManager talks H.323 to the 3640 in Mexico and talks MGCP to the gateway in Atlanta for the call control. When a call is placed from a PSTN phone in Mexico to a PBX phone in Atl, the call setup will first take place via H.323 between the 3640 and CCM and via MGCP b/w the Atl gw and CCM. After the call setup is complete, the audio stream should be connected directly between the 2 endpoints (ie 3640 gateway and the Atl gateway).
You should check for IP connectivity between the Mexico 3640 and the Atl router. Note, the call setup could complete successfully b/c both devices can reach the CCM, but can they reach each other when CCM steps out of the picture?
The following URL will also provide more good info on troubleshooting one-way audio.

Hope this helps.

Cannot make outside call (H.323 gateway and CUCM 6)

I cannot make outside calls. I am using H.323 gateway configuration and CUCM 6. I have attached configuration file and debug file. I configured H323 gateway and route pattern in CUCM. Please let me know if this is a configuration issue or telecom issue.

Hi 9tysixuae,
I can see that call is hitting the analog ports but from there on it generates error 34 which means circuit not available. You can try the following :
1. Plug Analog phone and verify if the circuit is fine ?
2. Try putting signal ground start on the voice port and see if that makes any difference.

Trending PRI usage on an H.323 Gateway

Hey guys!!
Does anyone here know of any software or tools or any cisco "in house" method of tracking PRI usage on an H.323 gateway? We would like to see here what usage we're getting out of our PRIs.
Thanks,
BR

Hi Brent
Yes, you can use SNMP counters on an H.323 Gateway to track the number of concurrent calls.
A sample OID is 1.3.6.1.4.1.9.10.19.1.1.4.0 (you will need to check this)
I use MRTG/PRTG to track this and produce pretty graphs.

MCU 3515 EMP Registration failed

Hello,
I have a problem with a MCU 3515. I can't make the EMP to register to MCU. The message received is:

Can help with that?

Hi Dan,
Did you managed to fix this problem? I have the same problem. I am running version 5.0. I have tried restoring to factory defaults and configuring from scratch but no joy.
Many thanks,

MCU 3515 Error: Wrong Moderator PIN

Hi all,
I have an error (Error: Wrong Moderator PIN) with the MCU 3515 when I try to create a new conference.
Any idea about that?

Here is the procedure In the PIN Settings tab you can define a policy for the use of PINs for accessing a conference.
Step 1 In the Administrator interface, on the sidebar, click MCU (if not already selected).
Step 2 Click Services. Select the service you wish to configure and click Add.
The Automatic Service Definition dialog box appears.
Step 3 Click Advanced Management and Security.
The Management and Security interface appears.
Step 4 Click PIN Settings.
Step 5 Select Force conference PIN protection if you want user to enter a PIN when creating or entering a conference using this service.
Step 6 Select Do not to ask for conference PIN when dialing-out to invitees if you want only dial-in participants to enter the conference PIN.
Step 7 Click OK.
Then you don't get this error. Try it.

MCU 3515 conference control

Hi, i have an mcu 3515 12 ports, i have already configured the IP adresses of the MC and EMP..etc.
I configured a service that use SCCP, but in the Conference control i can't use this service to create a conference. Does Conference Control of mcu support creation of SCCP conference?

On entering the MCU web page there is an option to enter a conference id in order to view the conference details.
This is not operational.
Workaround:
Log in as administrator or operator. Select the Conference Control button on the left hand side of the page. A new page with a list of the current conferences is displayed. Select the conference of choice to view the conference details.

Mode cli MCU 3515

Hello,
I have an mcu 3515. I would like configure the EMP port setting. What is the command to do this ? Is there many commande to troubleshoot in cli mode ?
Thanks,

Hi!
In the VxWorks type the command "modifyTargetDevice". After that you will see the menu configuration.

Does MCU 3515 supports direct ip dialling?

Hi,
Does anyone knows if MCU 3515 supports direct ip dialling? we want to establish videoconferences but participants should be able to dial to an IP address without registering to a gatekeeper.

Direct IP dialing is supported on MCU 3515 only in version 5.6. In order to do so, you have to do the following :
- Put a fake gatekeeper address (if you don't have any gatekeeper) i.e. 1.1.1.1 (do not use an ip address ending with 0).
- Enable Auto Attendant IVR
- Choose a Default Service Prefix previously configured as Service Type : "HD/SD Continuous Presence".
- Disable "Register conference ID" on Advanced Settings.
Now you can Dial through the MCU IP address.

H.323 Gateway Registration

Hi,
I am trying to configure H.323 to a CUCM cluster. I was able to configure using the IP address. However when I tried using the hostname, it is unable to get registered. According to the Cisco doc help:
Device Name: Enter a unique name that Cisco Unified Communications Manager uses to identify the device. Use either the IP address or the host name as the device name.
Should we enter the hostname as configured on the IOS Gateway or hostname as configured on DNS server?

In the device you would be using the hostname that must be resolved by DNS.
hostname# resolve to IP address of the GW.
