It is not possible to configure Asterisk for this. The chan_pjsip
module only does normal reinvites with SDP when configured to pass
through MOH signaling.


This is the answser I feared ;-)
Thanks for replying.

If someone has a clue for alternatives (softphones, hardphones, ...), 
I'll curious to know

It is not possible to configure Asterisk for this. The chan_pjsip module only 
does normal reinvites with SDP when configured to pass through MOH signaling.

[asterisk-users] How to defer SDP in ACK for unit testing purposes

[Olivier]

Hello,

I think I met a case similar to the one solved by [1] . Quoting this case :

* res_pjsip: Handle deferred SDP hold/unhold properly.

  Some SIP devices indicate hold/unhold using deferred SDP reinvites. In
  other words, they provide no SDP in the reinvite.

  A typical transaction that starts hold might look something like this:

  * Device sends reinvite with no SDP
  * Asterisk sends 200 OK with SDP indicating sendrecv on streams.
  * Device sends ACK with SDP indicating sendonly on streams.


Now, I would like to configure an Asterisk instance to act as those SIP
devices, ie to defer all SDP signaling in ACK.

This is for testing purpose as I would like to reproduce in a lab an issue
with those SIP devices.

1. Is it possible ? I can use any Asterisk version for implementation.
2. Alternatively, do you know any softphone "implementing SDP in ACK" ?
3. Alternatively, do you know any SIP hardphone implementing this ?
4. Suggestions ?
