What value should I set my Registration Interval to?

Problem:

Solution:

Registration is the event where your IP Phone (UA) contacts our system and tells it where you can be reached for incomming calls. The registration interval is the time (measured in minutes or seconds) between when your UA re-registers. Registration is required before you can make PSTN calls (see the Knowledge Base article on Error 205.)

Our sip proxy forces a 60 minute registration regardless of the interval specified in your VoIP adapter.
