[SR-Users] Request Timeouts

[Daniel-Constantin Mierla]

Hello,

can you paste here the full content of such INFO request received by
kamailio (as text)?

The 408 means that kamailio tried to forward it, but the target didn't
reply.

Cheers,
Daniel

I am still unable to resolve this, but I have verified all the INVITES to the ACK's and they seem ok.  I do get connected for about 30 seconds though, the call just drops after that and it does appear to be caused by the none response to INFO requests.

There are many of the very same INFO Request going from Asterisk to Kamailio; there is also another INFO request in the middle that was different (but only occurs a few times).  The INFO Requests do have ;tag in the To header.
