Forward Invite greatly delayed after Asterisk receives 302 Redirect

Hello,

I’m having an odd issue where my call forwards have stopped working when Asterisk receives a SIP 302 from a partner gateway. I’m having this issue on v 13.13.0 and 14.2.1

The situation should be that Asterisk receives a call from a registered softphone (Mike) -> Dials a peer (GW1) -> Peer returns 302 Redirect -> Asterisk forwards the call to an external Gateway (GW2).

This was working fine, and suddenly it changed. Now the call seems to wait for a timeout; after the softphone and sends a CANCEL, Asterisk sends the redirected invite.

In the samples below, the NOT Working Call shows a delay of 40 seconds between the "Now Forwarding … " message and the "Not accepting call completion … " message. When tracing the calls on both gateways, Asterisk does not send this invite until after the call is torn down. On the working call, the invite is forwarded immediately.

Further, I can set this call up with channel originate command. There is still a long delay, but eventually the channels are bridged. On this CLI originated call, the SIP/Mike-00000009 was setup for 40 seconds before the call progressed:

As always, you need to provide the SIP debug output for the call. However it looks to me as though the new destination is where the problem is occurring.

Thanks, david551.

Sip Debug is below (sorry, I don’t have permissions to upload)

The destination gateway for the forwarded call is 10.45.250.20, however, Asterisk does not send the invite until after it receives the Cancel message from the originator:

You didn’t mark your log as unformatted text; that is essential for VoIP logging on these forums.

You appear to have screen scraped the log, so there are no time stamps; time stamps are essential for any problem associated with unexpected delays.

The caller seems to have abandoned the call soon after the redirect, and before any attempt has been made to initiate the redirected leg. The only indication of how soon is the lack of any intervening OPTIONS.

Strangely, in spite of the incoming all having been abandoned, Asterisk is proceeding to initiate the redirected leg.

The peer sends Trying, to stop retransmission of the INVITE, then fails to send any further response. The problem lies with TELES.

After an unknown amount of time, Asterisk aborts the outgoing let.

The log cuts off before it send the ACK for the CANCEL transaction.

The Trying means there isn’t a routing problem associated with addresses used in the early dialogue. However, it is possible that the reply is too large for the return path.

Thanks; this ought to come out cleaner:

 - Asterisk receives 302 at 10:18:50 and sends ACK.
 - There is no 181 sent to the originator, and no call other call progression until the CANCEL is initiated at 10:19:22 (32 seconds after Asterisk receives the 302)
 - Then at 10:19:30 we have "app_dial.c: Not accepting call completion offers... " and the INVITE is then sent to the TELES (40 seconds after Asterisk received the 302)

The timing of the CANCEL’s makes more sense now. It has locked itself into sending the INVITE, so doesn’t notice the caller has given up.

I would say the most probable cause is that you are not getting a response to to a DNS PTR query on 20.250.45.10.in-addr.arpa.

david551,
I’ve originated the call from a new soft-phone that doesn’t automatically tear down the call; this allows the call to remain standing until the Asterisk send the forwarded invite, and the call completes.

The 302 arrives at at 11:59:25
Asterisk sends 181 at 12:00:05 (40 seconds later, again)
I’ve truncated Subscribe / Notify and VERBOSE output below in order to the character limits of the post

Thanks a lot for your help so far.

david551, that did the trick!! Thank you so much!

There was an IP routing change upstream in my network and I no longer had access to the configured nameservers. To test, I commented out the configured name servers in /etc/resolv.conf and these redirects are back to working.

Thanks!
