VoIP strange behavior (calls terminated)

[aretsu]

Hello,

I have two network nodes (3662) running VoIP between them, but we are having a rare issue.

The calls are completed well, but after a lenght of time (not fixed) the call is terminated without user intervention. The calls could last from 2 minutes to 30 minutes.

The connection is a VoIPoFR. I am using FRTS with fragment, and ip rtp priority. I might think I having a QoS issue, so I used RSVP to reserve some BW to this calls. I configured RSVP as follows:

On the intf:

ip rsvp bandwidht 204 204

On the dial-peer:

req-qos controlled-load

Then I tried to use " show ip rsvp reservation", "show ip rsvp sender" and "show ip rsvp installed". Do I have to do anything else to see these reservations?

If you think it is not about QoS, what else could it be?

Thanks!!!

I would also save some bandwidth by enabling cRTP and VAD.

Hi Alex -

We'll need to see some debugs from the call disconnect to determine why the calls are dropping. Can you capture:

- debug voip ccapi inout

- debug cch323 session

during the time when the call drops?
