Solved: Integration with asterisk solution

chingkiatlee · ‎10-12-2011

I plan to setup a normal integration with Asterisk (Free VoIP Solution) with Cisco Router 3725. The connection as below

CUCM -> (UTP) -> Cisco 3725 -> (E1 back to back cable) -> Asterisk Server -> (PRI) -> Asterisk Server outside

I do able to established the D-Channel connection with Asterisk Server locally. But when i do a call, the RTP failed to stream out.

The calling number can be display on the called user & vice-versa. But not the RTP package.

But what i found out is the Asterisk Server is only accepted G711.alaw codec (correct me if i am wrong) but my CUCM calling out is using G711.ulaw codec. So it there cause the problem?

CUCM version is 7.1 but the 3725 IOS SCCP only supported up to CUCM 3.4, so i failed to use the trancording.

So is anyone have the solution?

Hi,

Can you post the show run from your 3725 router.

Hi acampbell,

FYI.

The D-channel is working fine & the signalling do pass thru, only the RTP does not work.

Not audio for both side.

ashok_boin · ‎10-12-2011

Hi,

Asterisk do support other codecs.

With best regards...

chingkiatlee · ‎10-13-2011

Hi ashok,

Do this supported for Qsig connection?

Cause based on the engineer, he do said it only supported for SIP trunk.

Correct me if i am wrong.

ashok_boin · ‎10-13-2011

Hi Lee,

Yes, Asterisk does support QSIG a long back.

Pls see the article in 2005 published in network world magazine.

http://www.networkworld.com/news/2005/111605-asterisk-voip.html

Can you please post any debugs from 3725 to Asterisk (signaling + media)? And also, what's the relevant config in the above shared config for Asterisk server including interface?

Regards...

-Ashok.

With best regards...
Ashok

ashok_boin · ‎10-18-2011

This is not helping much.

Can you pls try with "debug voip ccapi inout" and share the output? If needed, you can perform "debug vtsp rtp" command to debug RTP packet debugging later.

Regards...

-Ashok.
