I have no idea if this is actually the case or not (logs should probably confirm this) but it's possible that the subsequent re-invites being sent by FS are session timer refresh requests. If your gateway advertises support for session timers, but doesn't respond to re-invites, that would be a problem with your gateway. Of course you could disable session timers on FS if that is the case. Best, Colin On Mon, May 1, 2017 at 3:13 PM, Charles Bujold <cjbujold@accra.ca> wrote:
Hi,
Getting a strange issue, all incoming calls work great, but outgoing calls are getting dropped.
Initially though that it was a NAT issue but verified the NAT and it is working properly. The proper external IP is being used and the gateway is registering with the service provider without issue.
Checked the call flow with sngrep and wireshark and found some strange issues.
1. From my end, making the outbound call I see the call being connected and I receive a 200 OK that the call is connected and I have a connection. It will last about 1.5 minutes while at the same time I see 5-6 INVITE being sent from my Freeswitch to my service provider and then a BYE that it is hanging up.
1. From my service provider, they see the call established and then: SIP/SDP 82 Request: INVITE sip: telephonnumber@IPxxxxxx:5060; transport=udp, in-dialog
The question is what is the “in-dialog” it seems to be causing the call to not be recognize that it is active and INVITE being generated and not being answered which causes the Bye Command to occur.
Not certain how to fix. Any suggestions would be appreciated.
