    I have setup elastix 1.6-12. I have two types of phones Cisco 7940 and 7970. Th problem is when we are calling from a 7970 to a 7970 or 7940 the call drops in exactly 20 secs. If we call from 7940 to 7970 the problem is not there. Also for call to / from external the problem is not there.

    Need help as I am quite new to this and have been at it for many days and been reading on the sites but with no success.

    Did some more debugging and have found that the phones cisco 7970, is sending out invite request and after the sixth attempt hangs up due to no receipt of ack signal.

    Have tried other phones Cisco 7940, Polycom 301, Linksys 942, but found that it is only when the call is initiated from 7970 to any of the above phones it hangs up in 20 secs.

    Please i really need some help on this. Is there some procedure i am not following on this forum as to not get a response.
