Call goes in one direction

Volodymyr Khrystenko · ‎10-10-2013

Hello.

I have the next scheme:

9971(1000,1003) --- cisco 3945 ---- cisco 2901 --- 7742(1020)

Calls from 7742 goes to 9971 but if I dial number of 7742 on 9971 - I get immediate drop and complete silence. What it could be? Dial peers config:

3945#sh run | s dial

dial-peer voice 1001 voip

destination-pattern 1020

session protocol sipv2

session target ipv4:10.2.4.254

----------------------------------------

2901:

dial-peer voice 1000 voip

destination-pattern 100[0-4]

session protocol sipv2

session target ipv4:10.2.4.120

Hi Volodymyr.

Where IP Phones are registered? (CUCM/CME).

In case of 2 clusters of CUCM, did you check if the incoming calling search space is correct to call those extensions?

Let me know

Regards

Carlo

SIP/2.0 488 Not Acceptable Media - this message most likely means that there is a codec mismatch issue. Please provide dial peers configuration from both sides.

To: <1>; - that's strange, do you really have a phone with number 1 registered? Could you provide full telephony-related configuration from both gateways?

Andrey Chertolyas · ‎10-10-2013

Hello,

As I understand, your second configuration is from 3945, not from 2901 as you indicated, is it correct? Please check it and correct accordingly.

At least you should implement this commands on your 2901:

sip

bind control source-interface GigabitEthernet0/0

bind media source-interface GigabitEthernet0/0

It is needed to specify the particular IP address to bind the SIP server to make sure that every SIP conversation originated on 2901 would use the IP address of gi0/0 which is 10.2.4.120

Another thing you can change is to add the address of originating interface on 2901 (which is 10.2.4.120) to 'ip addresses trusted list' on 3945, since it is not clear if you have it specified. Then make a call and gather next debugs in case it still doesn't work:

debug voice ccapi inout

debug ccsip messages

BTW, 10.2.4.254 is the address of gi0/0 on 3945, right?

Kind regards,
Andrew C.

Kind regards, Andrew C.
