Weird one.
I'm using Incredible PBX 13 ISO.
First site uses Cisco / Linksys spa508g, 8-line phones. The only thing I hate about these phones is that they're so difficult to Google for problems about - they're the same as the other SPA Sipura things, but other people might have SPA504G, or SPA502G, or SPA303. Googling "Cisco asterisk" returns results on all the 79xx actual-Cisco phones. If it was a Polycom, I would just googling "Polycom Soundpoint asterisk sip unreachable" for example.
Anyway, model-designation rant over:
They were OK with single line configured.
When 2 lines were configured to different extensions, I found that the first extension would become "unreachable", either through qualify, or with no IP address showing when doing sip show peers.
I removed the additional extension configuration on the handsets, and played around some more, NAT settings (causes sip info or options keepalives I think), register timeouts, etc, and it was OK in the end. Register timeouts didn't sort it (the problem still happened, but it fixed itself sooner each time). I think giving up on the multiple extensions sorted it. I tried different SIP ports for each extension, even though this isn't necessary because the phone knows what account the SIP packet is intended for.
Now I set up a new system today, with the same phones, but the addition of a DECT Gigaset N300IP (+a540h handset), and they all seem fine, except for the Gigaset N300IP, which within the first hour of testing, would be unavailable and the calling Cisco phone would show "service unavailable" intermittently when trying to call to the Gigagset internally. This was just today and I haven't looked into it more, but I suspect it's the same problem and I expect to be hearing about it tomorrow.
The only thing in common, I think, is that they both have the same Netgear FS-728 poe switch.
Any ideas what might be wrong?
