IP phone keepalive process

I am running some tests on a demo platform with CCM 3.2(2c) in an IPCC environment.

Due to the network configuration I got some reset on a remote IP phone(remote = not on the same IP segment, in our case).

I know that the CallManager keepalive timeout process is triggered when the IP phone doesn't answer 3 successive keepalive packet sent every "StationKeepaliveInterval" value (defaulted to 30s.

I circumvent the phone resets, by increasing this value (I put 3mn). But I think it is more clever to increase the number of missing keepalive answer than increasing this value.

I wonder to know if this number of 3 missing answers can be changed.

Does anyone has an idea ?

Thank you. Bernard

Looks like you are hitting the bug CSCdy86262.

Re: IP phone keepalive process

Thank you for your answer, and you put the finger on my original request, I don't want to increase the StationKeepaliveInterval, I would prefer to increase the number of missing keepalive responses (which is currently 3) before declaring the phone "Unregistered". My concern is to know if this value of 3 can be changed. That would be more clever than increasing the keepalive interval which has some side effects like the one you address.

Do you know if we are able to increase this figure of 3 missing keepalive, and how ?

Thank you for taking some time to answer.

Regards. Bernard
