RFC3264 in SIP trunk IPV4 0.0.0.0

[iantra123]

Hi all,

We experiencing problem with Offer/Answer in the SIP Trunk with a Huawei MSC3000

The problem appears in CUCM V6, to V8

How to change the SDP parameters, when CUCM side make Hold or Supplementary services

from

c=IN IP4 0.0.0.0

a=inactive

to

c=IN IP4 X.X.X.X

a=sendonly

or a=recvonly

It seems that the Huawei side doesn't accept or understant the IP address 0.0.0.0

or the missing part of the value sendonly or recvonly

regards,

Antra

Hello,

there is no way to change it in call manager, i think what you can do is to introduce CUBE and that can change those parameter but i'm not sure as i havent done that before.

thanks,

Hello,

Tahnk you for your response.

I've tested with an asterisk, and i've found that it working if the asterisk is between the two system.

so i'll try out with the CUBE.

Hi Jindal,

You're right. the only solution is the CUBE.

But my new problem is that i'm using an ISR 2800, and just for 30 calls, I have 70% CPU and 45% Memory usage.
