[Freeswitch-users] Longtime working user's phone now disconnecting

[Sean Devoy]

Hi,

I have an emotional user who now claims her phone fails at least once a week and everyone else's must be, but no one has ever reported it!  My very favorite kind of complaint - entirely founded in emotion, myth and misunderstanding.

In any case, I called her.  I spent 4:11 listening to her complain, but not be able to sight a single instance I could research.  Then <CLICK> the connection was lost.  She claims she did not hang up, the line went dead.  Perhaps there is an actual problem after all.

I will add at least one of the errors she reported would lead me to believe there is a hardware (or power) issue on her desk phone (Cisco SPA540).  I did look on the phone after the dropped call and the phone did NOT reboot and said it was still registered from 45 minutes earlier.

Just FYI: The problems are reported to have started when COMCAST replaced their DSL and they got new external IP addresses.  The phones are NATed.

Can someone tell me what [BREAK], [NORMAL CLEARING], then "port ending bridge by request from write function" means?
Just for background, this was an internal ext to ext dial in separate "domains" on my FS server.  NO IVR involved.

Here is a log excerpt:

Any ideas where I should look next or even what the problem is?
NOTHING has changed on the server for months and months.  The FS version is rather out of date, but has been stable for a long time.

Thanks in advance.
Sean
