[Asterisk-Users] Asterisk, Tenovis, Fritz, capi problem
Background: We are currently implementing an Asterisk based solution for a customer to enable teleworker phone access. We have connected an Asterisk box running SUSE 9.3 with an AVM Fritz PCI ISDN card installed running CAPI to a Tenovis box. Softphones using SIP (referred to as SIP user) have been configured and can register no problem with Asterisk. The SIP users can call each other with no problem. Problem: Incoming calls to the SIP users work fine, but outgoing calls do not. Outgoing calls ring the called number no problem (dialing using chan_capi works fine), but when the called number answers, Asterisk does not receive any notification that the call has been answered, and hence the softphone keeps ringing. If the hash (#) is pressed on the called phone, the call is then shown as answered, Asterisk sees it as answered, but there is only oneway voice. The called party can hear the SIP user, but the SIP user cannot hear the called party. Asterisk also does not get notification that the call was terminated if the called party disconnects the call. Attempted Solutions: We believe this to be a DTMF problem, but are not sure. We have tried changing the DTMF in the sip.conf and capi.conf files, but nothing seems to solve the problem. If anyone has solved this problem, or had any experience with a similar setup, we would greatly appreciate any assistance.
