I have setup a dial-peer to connect my call. I was able to connect to the other end(outbound call). the problem I'm facing is that for some reason, the other end can't hear anything from me, but I can hear from the other end.
Thanks.

I just looked into my system and saw that "show clock" is showing incorrect date. The document you gave me did mention incorrect "clock" could be the cause for one way voice issue.
What I wanted to understand is the difference between the controller clock and the clock displayed by "show clock". Are they the same or totally different?

Hi,
I searched for the difference between the clocking and got the following document. And as per this document, I guess both are different clocks.
The one they've mentioned in troubleshooting document is Controller Clock and not the one which can be seen by Show Clock command.
Refer to the document to understand the clocking configuration for controller.
In your case, I guess you need to check your routing i.e. if phones are in different subnets then there should be routing between them or if they're in different VLANs then inter VLAN routing need to be done, and if your router is MGCP or H.323 gateway then you need to run commands bind media source interface and bind control source interface. These are the main causes of the One voice issue.
Let me know your exact topology so that I can understand what exact problem you're facing.
Regards,
Amit.

call will come in via tdm pri -> gateway transfer call to a h323 server - > h323 server receives call and sends call back out to PSTN
my gateway and the h323 server are in different network. I dont have any control over the h323 server.

Hi Vinh,
you haven't told me if you are able to ping to the other end where you're calling.
Regards,
Amit.
06-09-2010 11:20 PM
I tried to ping but wasn't able to. I think they just disable "ping" on their system.
06-10-2010 03:15 AM
If you're not able to ping then you need to check the routing. And get a confirmation from them if they have really disabled the ping.
As far as I know, you at least should be able to ping.
Regards,
Amit.

Yes I verified with the provider. They disabled imcp.
I'm really at lost as what is needed to be done. I had debug voip rtp. But couldn't get much out of it.
Any advices or pointers would be greatly appreciated.
