[Asterisk-Users] Polycomm IP500 dropping incoming calls

[rsenykoff at harrislogic.com]

Hello everyone. 

I can place outgoing calls no problem with my IP500 (using teliax as our 
provider). Thing is, when a call comes in, 90% of the time when I pick up 
the handset it drops the call immediately. I turned on SIP debug, and have 
listed my extension config from sip.conf. Any help is greatly 
appreciated.... sooo close.... TIA! -Ron

Figured out it was a NAT issue. We were using 1-1 NAT behind a Sonicwall. 
Changed it to simple port forwarding and all is fine.
