[Asterisk-Users] Cisco to * problem

[Alex Barnes]

I don't know anything about config of a Cisco 3640, do have a Cisco 5350
and have never seen it send SIP messages with multipart payloads.  So
can't really help you on that front.

However I can tell you what that means.

The INVITE request coming from the Cisco has
"multipart/mixed;boundary=uniqueBoundary" as the type of payload in the
message.  Asterisk is expecting / requires "application/sdp", in fact I
would bet that most SIP endpoints would only support "application/sdp".
The payload in INVITEs (am simplifying a little) is where SIP devices
detail what their media capabilities are, so that the other end point
knows what types of audio / video it can send.  Taking a complete guess
I would suggest start by looking into audio codec settings on your Cisco
3640.

Not much help I know but hopefully will give you a start.

I am trying to connect a Cisco 3640 terminating a PRI to * with SIP.
When I call into the PRI, the Cisco answers the call and sends it on to
*, however there is no audio.  The clue is, the following message out of
*:

Oct 15 07:50:58 NOTICE[1094289728]: chan_sip.c:2679 process_sdp: Content
is 'multipart/mixed;boundary=uniqueBoundary', not 'application/sdp'

Looking at the * code, this looks like a mismatch of some sort between *
and Cisco, but I have tried every combination of codecs I can think if,
and the problem doesn't change.  Has anyone seen this message, or have a
clue as to what it means?

TIA

Dear Friends of Ubiquity Software: 
 
As you may have noticed, Ubiquity Software began using the web domain ubiquity.com earlier this year in addition to the previously established ubiquity.net for our website and email communications to you.  However, since that time, a dispute has emerged with respect to actual ownership of the ubiquity.com domain.
 
As an international software company founded over decade ago, you can always reach Ubiquity Software under the website www.ubiquity.net <http://www.ubiquity.net/>  and via email at @ubiquity.net.  However, we have also chosen to expand our domain to the more specific www.ubiquitysoftware.com <http://www.ubiquitysoftware.com/>  for web and @ubiquitysoftware.com for email communications.
 
Please use either the historical ubiquity.net or begin to use the new ubiquitysoftware.com domain for all email communications to Ubiquity employees from now on. 
 
Thank you.
 
Regards,
