Wondering if anyone on here can help with a niggling issue: One of our
extensions is unable to make attended transfers at all.
The phone in question is an Elmeg ip290, and works fine for direct
transfers. However, on attempting to make an attended transfer, the first
leg succeeds (the inbound call is placed on hold and gets MoH, the Elmeg
user announces the call to the target extension), but upon completing the
transfer, both parties get MoH, not each other.
There is an entry in the asterisk logs as follows:
chan_sip.c:6930 get_refer_info: Supervised transfer requested, but unable to
find callid '3c30e86b0ea6-4zwcw5b9ycux@192-168-0-253'. Both legs must
reside on Asterisk box to transfer at this time.
The incoming call, the Elmeg and the target extension are all on the same
asterisk box. The Elmeg is behind NAT, but canreinvite=no and nat=yes are
both set in the appropriate sip.conf sections for both the Elmeg and the
target destination.
Can anyone shed any light on this?
Thanks in advance.
Regards,
Chris
