I can't connceting VoIP

[cactus95]

I have HQ Router(R3662) and Branch site router (R2811)

But there does not connect each other

So, I had debug Branch site Router

but I can't get any states without debug voip ccapi all

---------- debug --------

Branch#debug rtsp all

All RTSP client debugging is on

Branch#debug voip application all

All application debugging is on

Branch#debug voip vtsp all

voip vtsp all debugging is on

Branch# debug voip ccapi all

voip ccapi all debugging is on

I had guess that DSP module is broken

Waht is the matter ?

[Chester Rieman · Accepted solution]

Not enough info - H323? versions? configs?

dsp output?

[cactus95]

I'm Sorry for my carelessness

We use for H.323 and Configs reads as follows

and than I had get the other debug state

I had solved this problem so hard by help for Cisco TAC

that problem is the section of satellite communications.

Cisco TAC say that "the root cause might be the failure of TCP 1720 port connection for call setup of voice.

Although satellite modem always send TCP keepalive packets to source address of TCP 1720 port, the other side couldn't response of that.

I think that was the root cause of calling failure.

So, TCP timeout had occurred by above."

and than they suggested to use for GRE tunnel for voice traffic

and I success

thank you very much for Cisoc TAC Teams
