no answer calls to SIP phones disconnect after one minute

[Jose Carlos Silva]

Hi all!!! I wonder if you can give me some Help!!!!

I have an Call Manager 6 with Cisco SIP phones and Cisco skinny phones.

If a call came from the outside via E1 to a Cisco set and if no one answer, the call drop after two minutes but if I call to a SIP phone the call drops after one minute.

The Call Manager is connected through SIP trunk to another PBX and if a SIP set receives a call from that trunk and no one answer the call drops after one minute, also.

I saw the T301 for E1 and SIP and all are 180000 msec = 180 sec = 3 minutes, right?

So why the CM releases the call for the SIP sets after one minute and for the skinny after two minutes?

The customer wants that at least the call ring for about 3 or 5 minutes.

Can someone point me to the right direction?

Thanks on advance!!!

Best Regards,
