Hello all, I am new to Asterisk@home and am having a strange issue with both my new Grandstream HT-286 & BT-101. The issue is as follows: Example is with BT-101 (HT-286 shows same behavior) 1) Device registers to Asterisk 2) I can place a call via the BT-101 out my Zap or SIP provider 3) Conversation takes place (yay!) 4) I hang up BT-101 5) BT-101 will no longer dial out until: a) I give asterisk a "restart now" b) I place a call from another extension in my home TO the BT-101, answer BT-101, hang up BT-101, and all is well for another single outbound call Nothing is logged via "sip debug peer 7213" when the phone will not dial. After I reset it above, everything looks/works fine. This behavior also occurs with internal extension to extension calls between the BT-101 (7213) and HT-286 (7214). To me, it sounds like I have something incorrect with my extension configuration (teardown?) for both the BT-101 and HT-286, however, I also have 2 X-Lite softphones, with identical extension configurations as the Grandstream devices, and both of the softphones work flawlessly, and have for several weeks now. Here are my configs. First X-Lite softphone: [7211] username=7211 type=friend record_out=Adhoc record_in=Adhoc qualify=no port=5060 nat=never mailbox=7211@device host=dynamic dtmfmode=rfc2833 context=from-internal canreinvite=no callerid=device <7211> BT-101 (firmware 1.0.8.16): [7213] username=7213 type=friend record_out=Adhoc record_in=Adhoc qualify=no port=5060 nat=never mailbox=7213@device host=dynamic dtmfmode=rfc2833 context=from-internal canreinvite=no callerid=device <7213> Please let me know if you need any more of my configurations; any and all help would be appreciated. Thank you!
