Hi,
Sofia SIP sending incorrect offer SDP in 200 OK when the network resumes the
call after putting it on hold. The offer SDP contains "a=recvonly" attribute.
Also it does not advertise the complete list of supported codecs, instead it
re-uses the initially negotiated codec. Network uses delayed media scenario on
resuming the call. The offer send by Sofia SIP in 200 OK looks like the copy of
the answer SDP sent in the previous INVITE transaction made to put on hold.
How can I get the Sofia SIP to make a fresh offer in the re-invite scenario? At
least have the offer advertise "a=sendrecv" instead of "a=recvonly".
Any help in this regard will be very useful.
The call flow is as shown below
Sofia N/W
INVITE -->
<-- 100/180/200
ACK -->
<== 2-Way Voice ==>
<-- INVITE (SDP for On hold)
200 -->
<-- ACK
<== No Voice ==>
<-- INVITE (w/o SDP)
200 -->
<-- ACK (w/ SDP)
The SIP trace is given below:
