[Asterisk-Users] Polycomm IP500 dropping incoming calls

Wed Dec 29 07:24:48 MST 2004

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
