I am currently trying to develop a new module in freeswitch which requires
In this new mod, the primary decision making will be based on the multipart
text received in the SIP INVITE message.
So far, I am able to do the following:
1. upon receiving SIP INVITE, separate the received multipart text
2. do the required processing and take a decision based on this
Now I want to generate a new SIP INVITE (to a different user) having a
similar structure (i.e. sending out a new text message to the user along
with new parameters in SDP).
I was able to generate a SIP INVITE with help of switch_ivr_originate().
I was also able to add the required Multipart Text part in the INVITE.
However, I am not sure how to proceed with adding new SDP part....
(In below sample message, I was able to generate everything in Green but
nothing in RED)
So my question is this, where should I make changes to add to SDP.
Any help is appreciated
