[asterisk-users] how can I release trunks after transferring 2 calls connected on trunks between the same machines.
Hello, I made 3 questions because they are linked and actually dealing with the same need of releasing trunks after transferring 2 calls connected on trunks between the same machines. 1) I have a machine with Asterisk 1.4 connected with a SIP trunk to a PBX. A (on the PBX) calls B (a SIP phone on Asterisk). B answers and puts A on hold. Then B calls C (on the PABX) and does an attended transfer. How should I configure Asterisk to send a SIP REFER message to the PBX at the transfer ? I need it to release the SIP trunks and let the transferees talk through the PBX without involving Asterisk any longer in their call. 2) If I connect a first Asterisk via SIP trunk to a second Asterisk 1.6 and connect this second Asterisk to a PBX via QSIG. A (on the PBX) calls B (a SIP phone on the first Asterisk). B answers and puts A on hold. Then B calls C (on the PABX) and does an attended transfer. Provided the first Asterisk can send a REFER message to the second Asterisk, how should I configure the second Asterisk to make it send the message Facility: Call Transfer Complete to the PBX via QSIG at this transfer ? I need it to allow the PBX to reply with the message Path Replacement Purpose, have the QSIG trunks released and let the transferees talk through the PBX without involving the 2 Asterisk any longer in their call. Which hw/QSIG board shall I use on the second Asterisk to get this behavior ? Any PRI board ? 3) This is basically the same question of 2) but with a IAX trunk. If I connect a first Asterisk via IAX trunk to a second Asterisk 1.6 and connect this second Asterisk to a PBX via QSIG. A (on the PBX) calls B (a SIP phone on the first Asterisk). B answers and puts A on hold. Then B calls C (on the PABX) and does an attended transfer. At the transfer, the first Asterisk correctly sends TXREQ to the second Asterisk. How should I configure the second Asterisk to make it send the message Facility: Call Transfer Complete to the PBX via QSIG at this transfer ? I need it to allow the PBX to reply with the message Path Replacement Purpose, have the QSIG trunks released and let the transferees talk through the PBX without involving the 2 Asterisk any longer in their call.
