Dear SipX-Users,

i am still "playing" around with the Portech GSM Gateway and i have a 
interesting problem. i can make outbound calls via the gateway from the 
conferencing bridge, but i cant make outbound calls with my polycoms. i made a 
tshark while both calls and here is the result:

147.448046    10.1.1.85 -> 10.1.1.50    SIP/SDP Request: INVITE 
sip:[email protected]:5060;sipx-noroute=Voicemail;sipxbridge-moh=false, 
with session description

149.010682    10.1.1.85 -> 10.1.1.50    SIP Status: 200 OK

and when i call out from the polycom i get this:
