I have a Asterisk setup as a PBX registered with Broadvoice. On the inside, my analog phones are registered with it via a Sipura SPA3000 ATA.
It appears that about once a day Asterisk “looses” registration with Broadvoice. It is rather tough to debug because Asterisk doesn’t print much usefull information even at a log level 5. The only regularity I think exists is that the registration appears to working fine when there are no active calls. If there are active calls Asterisk seems to stay registered. I wonder if there is a problem if registration happens to expire during an active SIP call.
Has anybody seen anything similar? I have Asterisk version 1.0.5.
