Hi, I have actually 2 providers : p1 & p2 p1 is used as a DID only for incoming calls p2 is used for making outgoing calls I have 1 registered user : ext 1000 I have 2 GSM phones : GSM1 & GSM2 My dialplan is as : <include> <extension name="public_did"> <condition field="destination_number" expression="^(MY_P1_DID)$"> <action application="transfer" data="1000 XML default"/> </condition> </extension> </include> For incoming calls "1000" is ringing and i can make a call without any problem (GSM1 => P1_DID => ext 1000) But whene trying to bridge the incoming call to p2 gateway (GSM1 => P1_DID => P2_GW => GSM2), i can see that GSM2 is ringing but whene i answer the call i can't hear any audio ... This is my dialplan for the second case: <include> <extension name="public_did"> <condition field="destination_number" expression="^(MY_P1_DID)$"> <action application="bridge" data="sofia/gateway/p2_gw/GSM2_NUMBER"/> </condition> </extension> </include> Any help are welcome best regards
