Description:Have observed a problem with asterisk 1.8 (versions,, all behave the same) and using the manager redirect command to redirect two channels which are bridged together via dial command to alternate locations.

When the redirect is attempted, the following error is received on the second channel:
[Jun  4 13:06:29] WARNING[24411]: channel.c:5874 __ast_channel_masquerade: Can't setup masquerade. One or both channels is dead. (AsyncGoto/SIP/30-00000001 <-- SIP/30-00000001)

Have previously used this on multiple 1.6 version with no problem (manager.c was patched to include Extra channel options from 1.8).

Any help would be great, thank you.

We require a complete debug log to help triage the issue. This document will provide instructions on how to collect debugging logs from an Asterisk machine for the purpose of helping bug marshals troubleshoot an issue: https://wiki.asterisk.org/wiki/display/AST/Collecting+Debug+Information

Additionally, please include the exact manager commands used,  extensions.conf and point out the dialplan that initiates the two channels mentioned. Include a full log with DEBUG and VERBOSE at level 5 and point out where in the log the issue occurs

Have attached two files:
'dialplan.inc' which includes the dialplan relevant to issue
'issue_19948.log' asterisk debug of issue when it occurs.

This is example of command used to join channels together:
[Jun  5 11:05:36] VERBOSE[5022] pbx.c:     -- Executing [30@direct:2] Dial("SIP/18-0000000c", "SIP/30,45,gM(inboundlog)") in new stack

This is the http command used to redirect the channels:
[Jun  5 11:06:04] DEBUG[5036] http.c: HTTP Request URI is /asterisk/mxml?action=Redirect&Channel=SIP/18-0000000c&Exten=18&Context=callhold&Priority=1&ExtraChannel=SIP/30-0000000d&ExtraExten=1&ExtraContext=transfercleanup&ExtraPriority=1

This is the error which occurs:
[Jun  5 11:06:04] WARNING[5036] channel.c: Can't setup masquerade. One or both channels is dead. (AsyncGoto/SIP/30-0000000d <-- SIP/30-0000000d)

Please advise if require any further debug/logs.

Thanks Brent. That info should work for now. A developer should be able to look at it as soon as one is available.

I believe that you are experience this issue: ASTERISK-18975

Best regards.

Any updates on this issue? We have used multiple channel manager redirect for years without any problems on asterisk 1.2.
However, we have been experiencing this problem for quite a while on asterisk 1.8.7. It would be very important for us to have a correction.

Thanks in advance.

A potentially related issue was resolved in You may want to try reproducing the problem using that version (or later) to see if your issue still occurs.

If it does, please note in the comments here and I'll unlink the issue.

Is ASTERISK-19985 the potentially related issue that you are referring ? I have already tested with the patch provided in that issue and this problem persists. Never the less i will install a clean asterisk with the recommend version and will try to reproduce this problem.

Best regards.

By: Matt Jordan (mjordan) 2012-08-13 10:11:00.520-0500

It is.  If the issue isn't resolved in that's fine - I'll unlink the issue.

I can confirm that this issue and ASTERISK-18975 is not resolved for asterisk By adding one second delay like suggested in ASTERISK-18975 the dual redirect of two bridged channels will fail on masquerade.

Best regards.

It would be great to finally get this resolved. This issue has been holding back our development on some really cool real-time dashboard features for a very long time. Any ideas on a workaround for splitting two currently bridged channels and redirecting them to a meetme room using the manager api?

We have also been experiencing this issue since we upgraded to Asterisk 1.8 from 1.6. Whenever we try to redirect two channels, extra channel always gets disconnected.
We uses multiple channels redirect feature to put two channels into a conference.
Is threre any resolution to this issue?

Hi I seem to have been able to replace the same issue on Asterisk 11.1.0, I have tried applying that patch on Asterisk 11 but it does not compile. Is it possible to patch this version of Asterisk as well. We need this ASAP as we are looking to move away from Asterisk 1.6 which is which seems like its only version that Redirecting two channels into a conference works. We would like to get this working on Asterisk 11. Thanks

By: Richard Mudgett (rmudgett) 2012-12-13 10:08:40.527-0600

The patch will be merged into the active branches when it is ready.  The reviewboard patch is for v1.8.

By: Kayode (gltduser) 2012-12-13 11:34:18.224-0600

Thanks for the response, is there any way to facilitate the quick addition of this to Asterisk 11?

By: Thomas Sevestre (to) 2012-12-21 03:05:45.690-0600

Hello, has anybody applied this patch in production?
I've tested the patch on asterisk 1.8.13. It looks fine so far.

By: Deepak Lohani (deepaklohani) 2012-12-21 03:19:35.812-0600

Hi I have tested it with asterisk 1.8.16 and it is working fine.

By: Kayode (gltduser) 2012-12-21 03:48:22.947-0600

I have tested the Asterisk 11 patch on 11.1.0 and that works fine as well.
