Hello I am trying to configure Freeswitch, so that 2 telephones each one is connected to a fritzbox and at different locations can speak. The call rings but when the callee lifts up, call drops. I would appreciate if any body can help. Below is a log of the call Thanks in advance regards, Sherif 2011-12-12 07:38:32.098496 [DEBUG] switch_core_session.c:1164 Session 45 (sofia/sipinterface_1/sip:2004@78.138.90.31) Locked, Waiting on external entities 2011-12-12 07:38:32.101287 [DEBUG] switch_core_codec.c:146 sofia/sipinterface_2/2005@sip.server.com Restore previous codec PCMA:8. 2011-12-12 07:38:32.101287 [DEBUG] switch_ivr_originate.c:3228 Originate Resulted in Error Cause: 88 [INCOMPATIBLE_DESTINATION] 2011-12-12 07:38:32.101287 [ERR] switch_ivr_originate.c:2430 Cannot create outgoing channel of type [user] cause: [INCOMPATIBLE_DESTINATION] 2011-12-12 07:38:32.101287 [DEBUG] switch_ivr_originate.c:3228 Originate Resulted in Error Cause: 88 [INCOMPATIBLE_DESTINATION] 2011-12-12 07:38:32.101287 [INFO] mod_dptools.c:2355 Originate Failed.
