[Asterisk-Users] How do you avoid or reduce false hangups on X100P?
Hi Most of the threads in the list archive relating to X100P and hangups are about not detecting hangups. We have got the opposite problem. We have experienced an increased number of false hangups when connecting an X100P to an analog port of an ISDN terminal adapter. It happens more frequently on incoming calls than it does on outgoing calls. Often hangups occur after about 3-4 minutes into the call. I tried different X100Ps but without any noticeable difference. Different TAs produce slightly different results, but the bottom line is that the situation is far less stable than connecting directly to an analog line. I played with the various parameters in zapata.conf but it doesn't seem to make much of a difference. I even tried different versions of Asterisk and Zaptel, but the false hangups persist. BTW, the customer does not wish to convert his ISDN line to analog lines for a variety of reasons. Does anybody know how to adjust the zaptel driver so that false hangups can be reduced? thanks in advance regards benjk -- Sunrise Telephone Systems, 9F Shibuya Daikyo Bldg., 1-13-5 Shibuya, Tokyo, Japan.

If you find any solution, could you be kind > enough to tell me what you did ?I went into the sources of the zaptel driver and removed enclosing comments from some #defines which relate to ISDN terminal adapters, then rebuilt zaptel. There are also some parameters you can play with. Even if you don't know what the parameters mean, the technical support of the vendor of the ISDN terminal adapter should recognise them and be able to give you some hints what values might give you better results. YMMV, but this has stabilised the situation for our customer. hope this helps regards benjk -- Sunrise Telephone Systems, 9F Shibuya Daikyo Bldg., 1-13-5 Shibuya, Tokyo, Japan.
