One Way Voice: Cisco 2801 <-> Elastix (Asterisk)

[GleidsonG]

Hello All.

I'm facing a one way voice problem between a Cisco 2801 and Elastix.

I just configuring a dial-peer pointing the traffic from PSTN.

Caller from PSTN side can hears the Called from VOIP side.

The topology is

PSTN <--> voice gateway   <--> Elastix

Hi,

One way transmission is caused by IP routing
issues

From your gateway IP address 189.84.48.10
can you ping an actual IP phone that you are
trying to call.

Yes, I can Ping.

I used the debug voip RTP and I saw that the rtp packets are sent to asterisk instead of sent to the phone.

Its wrong, the destination of packet should be te machine where instaled my ip phone.

Do you know I can resolve this?

Hi,

Try running a

debug ccsip messag

Se if that gives a clue as to what address the pbx

requsts the rtp streams to use
