IS-IT--Management
New install. 2 locations using AT&T sip trunks. The ATT router is an edgewater router at both.
We have a fortigate firewall between us and them.
In bound has been working without fail.
But the inbound is sporadic at both sites. I can go 1 day or 5 days before we start having issues dialing out. It does seem that the issues are more in the morning than in the afternoon. We have been working on this for 6 weeks now.
I have tickets open with NEC, Fortigate, and AT&T in case you are wondering.
What ATT is saying is that that "... found an issue with the SIP set-up time in the Invite. It is set as 180 and it should be 900 or higher".
NEC is not sure to what they are referring exactly. I am not either. I am not convinced this is the issue, but this is first time in 6 weeks they have giving me anything to work with other than me trying to figure it myself.
Looking for Ideas.
Yesterday, I did put one of the locations directly on the ATT router bypassing the firewall, just for another test. Waiting to see the results.
