Here is my setup
7960(A)--Firewall/PAT--dsl---------Internet--------dsl--Firewall/NAT---7960(B)
| |
| |
7960(C)--NAT--cable----------------- -----dsl -- Asterisk
(A) can communicate with (C) only when C is configured with canreinvite=no. The
call gets dropped in few seconds if canreinvite is set to yes for C.
(A) and (B) can communicate fine when both sides have canreinvite=yes.
Since (C) is not working with canreinvite, traffic goes thru Asterisk server.
This brings the Dsl connection to asterisk to a crawl. It is so bad that even a
idle ssh connection gets disconnected.
Is it possible to configure C so that reinvite works. If not what kind of a
bandwidth should I have for Asterisk server. Currently it has a upload of 128K.
The codec currently getting used is ULAW. Even if I configure 7960's to use
g729, show sip channel reports as using ULAW.
Thanks,

As you are connecting endpoints together that are behind NAT, you would need multiple G.729 licenses - one for every device that would be concurrently talking to the Asterisk server. I do not believe that it is possible to configure C so that reinvite works, though I would be interested in how you do it if you are able to make that function without Asterisk being a media channel proxy (quasi-border session controller.) You should have at least 56kbps for G.729, in my experience, unless you have no other traffic on the end legs of the diagram. G.729 uses less than 32kbps during normal circumstances, but other TCP traffic needs to squeeze in (as you have discovered.) Your Asterisk server will of course need to have N*(leg bandwidth) capacity, where N is the number of legs active at any one time. JT
Hi guys, Don't want to ruffle feathers, but did I see Ratnakar's email address as being @cisco.com. Is Cisco thinking of using Asterisk? Just a thought.

Just a thought.Well if I was a large hardware manufacturer I would certainly be testing compatibility of my hardware with other popular stuff, since only a fool would think people are going to buy open standards based equipment all from one manufacturer. If cisco is doing some testing, great !, but I doubt they are actually planning to deploy asterisk corporate wide.>Welcome Ratnakar > >Peter > >From: rkolli@cisco.com >At 14:50 2/10/2003 -0700, you wrote: > >Here is my setup > > > >7960(A)--Firewall/PAT--dsl---------Internet--------dsl--Firewall/NAT---7960 >(B) > > | | > > | | > >7960(C)--NAT--cable----------------- -----dsl -- Asterisk > > > >(A) can communicate with (C) only when C is configured with >canreinvite=no.
