[asterisk-users] Polycoms, Attended Transfer and Canreinvite = yes

[Avi Miller]

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
