asterisk users - Aug 2006 - Polycoms, Attended Transfer and Canreinvite = yes

Hey guys,

I've been trying to change my Asterisk setups to use canreinvite=yes. 
I'm having a small problem with my Polycom IP501 phones and transferring 
calls.

If a call comes in via my ISDN BRI lines (using chan-capi), I can 
successfully transfer the call using the Polycom Blind Transfer option 
(Transfer -> Blind -> EXT -> Send).

However, if I try to use the attended transfer method, the call is never 
connected to the new user. When I hit transfer, the caller gets MOH and 
I dial the destination ext. Once the person answers, I hit "Transfer"

Now .. the MOH stops for the caller, but both phones are dead. The call 
is never reconnected successfully. On the console, I see this:

     -- Called 405
     -- SIP/405-0849cba0 is ringing
     -- SIP/405-0849cba0 answered SIP/401-084a0ba8
     -- Attempting native bridge of SIP/401-084a0ba8 and SIP/405-0849cba0
     -- Stopped music on hold on CAPI/V4BRI-2/92355400-25
   == Spawn extension (macro-dial, s, 10) exited non-zero on 
'SIP/401-084a0ba8<ZOMBIE>' in macro 'dial'
   == Spawn extension (macro-dial, s, 10) exited non-zero on 
'SIP/401-084a0ba8<ZOMBIE>'
     -- Incoming call: Got SIP response 500 "Internal Server Error"
back
from 192.168.1.128
   == Spawn extension (macro-dial, s, 10) exited non-zero on 
'CAPI/V4BRI-2/92355400-25' in macro 'dial'
   == Spawn extension (macro-dial, s, 10) exited non-zero on 
'CAPI/V4BRI-2/92355400-25' in macro 'exten-vm'
   == Spawn extension (macro-dial, s, 10) exited non-zero on 
'CAPI/V4BRI-2/92355400-25'

405 is the extension I'm trying to transfer the call to.

Any advice? I've been searching the list archives and the wiki, but 
can't find anything specific.

Ta,
Avi

Hi Avi,

I had a similar problem. Have extension 405 put the call on hold (after 
the transfer) and then off hold. I am willing to bet it will bring back 
the audio stream. I posted something similar a few weeks ago and if 
anyone thought it was a bug, to let me know what information I needed to 
send in to report it, but no one replied.

Anyway, I noticed it happening on the latest release of asterisk. I 
rolled back my installation so I am on asterisk 1.2.9.1, lib 1.2.3, and 
zaptel 1.2.6 and that corrected the problem for me.

I just ran an SVN update to attempt resolution of this issue and now there
is a completely different issue...    Very strange.

1. inbound call comes into phone A and is answered.

2. transfer button pressed

3. number of phone B is entered

4. phone B rings and is answered.  audio between A and B is good.

5. transfer button on phone A is pressed to complete transfer and is
completely ignored.  only the conf button appears to function.

Can anyone else try todays code with Polycom 1.6.7 and see if they get the
same result?
