[Asterisk-Users] RE: Cisco 79xx and SIP 7.5 Problems

[Brent Torrenga]

Try 7.4 (P0S3-07-4-44). Notice on voip-info.org the comments about 7.5 being
buggy with some sort of registration issues (if I recall). Also, voip-info
reports 7.4 to be stable. If you read the Cisco changelog, you'll see LOTS
of bug fixes up to 7.4 (no new features, just fixes). I THINK one of the bug
fixes was that if call-waiting was disabled, it had no effect, and still
used call-waiting (as you correctly report). Good luck!


>I recently updated my phones Cisco 7960 phones (3 of them) in a high volume
call place, where the Secretaries use >the 7960 phones to answer inbound
calls, as many as 15 simultaneous calls between all three of them.
>Since then I have had only constant problems, mainly that after 3 calls on

the 4th call) the phone freezes, they have had this happen to them

problem, so I downgraded them to 7.1. Since then (around >5PM EST yesteday)
it didn't happen *yet*. So I'm assuming it has to do with the firmware.
>So my question is, is anybody else using 7.5 firmware?.

>I also noticed that with 7.5 firmware callwaiting has to be enabled for the
second call to be able to come in, otherwise the phone returns a Busy here,
while with the older versions it could have been disabled and it worked
fine, the phone only returned busy here on the 7th call.
So I had to enable call waiting, the way I did it was that in the
SIP<mac>.cfg file I added
call_waiting: 3
>I'm not sure if this is related or not, but that was the only change I had
to do to the config files.
