[Freeswitch-users] Attended transfer - no audio

[Jan Kubr]

Hi,
we have a Freeswitch server on a public IP and a few phones behind
NAT. The phones are configured to use STUN and can register and call
each other fine.
The problem is that after attended transfer (using the mechanism the
phones provide - REFER) is finished, the two parties can't hear each
other. This problem doesn't occur when the phones are in the same
subnet as Freeswitch.

I know this isn't enough information to solve the problem, but do you
have any hints on how to debug this? Are there any specific Freeswitch
settings that could help us?

Thanks,
Jan
