thanks, managed to fix this, problem was carrier was sending the re
invite but it wasn't reaching FS even though i had ports open and both
my server and carrier server were able to talk to each other for
outgoing calls, my FS is on a public IP so NAT isnt an issue and i had
to explicitly add a allow rule for FS external SIP port and strangely
the re invite started reaching FS and FS started responding, my other
problem is i want FS to just reply to the re invite after which the
carrier sends a ack but dont want FS to renegotiate codecs because the
carrier re invite has SDP with the same codec that the call is running
on so codecs will not change but they just send the re invite to prevent
fraud which needs to be answered to prevent call being dropped.
is there a way to make FS respond to the re invite but not try and
renegotiate codecs coz currently i see messages such as renegotiating
codecs and then no change.
