Registration Issue (Cisco phone)

Post by lysack »

Hi,

I have a Cisco SPA508G (with FPL unlock key) and have frequent registration issues.

Every few days (not a regular pattern), I notice that I can't register with the FPL server. I'll see a "Failed - No Response" error. If I change SIP ports on my phone from 5060 to say, 5061, it will register and will work for a number of days and then fail again. If I change the port it will work again but fail again later and so on.

I have two other VoIP providers and they are work fine on the same phone (I usually keep each provider on a different SIP port)

Any thoughts on this one?

Thanks.
