[Freeswitch-users] SIP trunk Cisco-Freeswitch: Cannot return from HOLD

[Yehavi Bourvine]

Hi,

  Cisco sends the SDP in the ACK. The problem is that Cisco sends
'sendonly" in SDP and FS replies also with "sendonly", and there is  no
apparent reason for this. This causes then a one-way audio.

            Thanks, __Yehavi:
