    Just wondering if anybody has encountered a similar problem as I have
    with recieving calls on Asterisk from a CISCO AS5350 (over SIP). I have
    dtmf relay configured on the AS, however, when someone calls in from the
    PSTN sometimes their digits are inputted twice, which messes up the

    If there is a better way to terminate calls from a AS without using SIP,
    that would fix this problem, then I'd be interested in that too.

    Have any ideas? If it would help, I could provide you with some of my
    config files.

    I ran into this problem but found if you use dtmfinband on both ends and 711
    on the local network you can get it to work and start changing things from
    there.... such as trying another codec, etc....
