CM5 - DTMF event timestamp causing problem

Hi,

I have a CM5 system, and have a sip trunk to a 3rd party voicemail system.

When I make calls from SCCP phones, and hit dtmf keys, the timestamp in event that is generated, is way off the timestamps in the RTP packet.

This causes the voicemail system to be confused.

With other sip endpoints (SJPhone for example) I dont have this problem.

Has anyone experienced this before ? I am guessing its a phone load problem, rather than anything to do with CM5.

Thanks
