Description:Iam testing the SIP TCP and am having trouble with the Moved
Temporarily SIP Message.  I am using 1.6 RC6

Once Asterisk receives the message I get this in the console:
Unable to create local channel for call forward to
'SIP/::::TCP@3451@10.10.20.31:5067' (cause = 20)

Below is the SIP trace.

Ouch, this is way off:

"-- Now forwarding SIP/1000-09648728 to
'SIP/::::TCP@3451@10.10.20.31:5067' (thanks to SIP/exch-0964c710)"

It needs to be "SIP/3451::::TCP@10.10.20.31:5067" There's obviously a parsing problem at some point along the line here that needs to be fixed.
By: Mark Michelson (mmichelson) 2008-09-22 16:15:55

I've made a patch which should correct the parsing error that was occurring before. I am operating under the assumption that you have promiscredir set to yes in your sip.conf file. If that assumption is wrong, please let me know.

Please test 13523.patch and report if it has fixed the problem. Thanks!

Applied the patch, get a different result now.

I think I applied the patch wrong.  I am going to untar RC6, apply the patch, make clean & make & make install.

Will report back.

I am still experiencing this issue after a rebuild of asterisk.

By: Mark Michelson (mmichelson) 2008-09-22 17:06:39

oh, I'm an idiot. I see what I did wrong. I'm missing an "else" case for an if statement in the patch. New patch forthcoming...
By: Mark Michelson (mmichelson) 2008-09-22 17:08:50

I've added 13523v2.patch which adds the missing else case I mentioned in my previous note. Thanks for finding the flaw with the first patch.
By: mattdarnell (mattdarnell) 2008-09-22 17:17:00

Looks like it works!  Great job.  I will keep playing with it and reopen the ticket if I encounter an issue.

When a promiscuous redirect contained both a user and
host portion in the Contact URI and specifies a
transport, the parsing done in parse_moved_contact
resulted in a malformed URI.

This commit fixes the parsing so that a proper
Dial string may be formed when the forwarded
call is placed.
