keep-alive RE-INVITE dropped calls
hi, im suffering call drops from carrier in roughly 15mins and i reported this to the carrier and they replied with the below: If the duration of the call was a multiple of 15 minutes, please make sure that you can properly respond to the keep-alive RE-INVITE that we sends every 15 minutes. i have no clue on how this works in FS so can any1 point me the right direction on how to sole this, we use FS to route calls from our switch to carrier -- Regards, Bipin
Sounds like a nat issue that their re-invite isnt getting to us. Review what you are sending in sip signaling to make sure they are the correct addresses and nothing in the network is blocking that request. Mike

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.

This will be referring to SIP session timers, which FS does support. Try collecting a SIP packet capture to see what packets are being sent and what the reINVITE packet gets as a response. On Tue, 2 Oct 2018 at 20:40, Bipin Patel <bipin@xbipin.com> wrote:
