Grandstream GXP2160 won't re-register after Register Expiration time is exceeded. In troubleshooting this issue I have found the section under Asterisk SIP Settings - Chan SIP (A) - Registration Settings. What do I set the minexpiry, maxexpiry, and defaultexpiry too? Are these settings in seconds or minutes and could anyone explain these settings please? My pbx & phones are both on an internal LAN. My SIP trunk is to an external VOIP SIP trunk provider. Once they go offline I get an error of: "Unable to create channel of type 'SIP' (cause 20 - Subscriber absent)". The phone still thinks it is registered but Asterisk says it is not. Any help would be appreciated.
