Question about blind transfers
by Alex Pierry 31 May '18

31 May '18

Hi all, I'm using the version 1.9.0 of Freeswitch with the following scenario: 1) One leg in park (the call center attendant in nailed up mode) channel uuid A 2) One incoming leg from customer. channel uuid B The call is bridged using api uuid_bridge and customer starts talking with the attendant. At this point everything is ok. But at some time, the attendant needs to transfer the customer to an external number located in another PBX. For this, I'm using the api uuid_broadcast to attendant's channel with att_xfer to dial an external number, as example bellow: uuid_broadcast A att_xfer::sofia/external/5000@192.168.0.24 When the external number answers the call, I set the attendant back to park so the customer can talk to the third-party leg (5000) - Blind transfer. What happens next is that B can hear 5000 but 5000 can't. The curious fact is that if B press any DTMF in his extension, 5000 starts to listen B normally. So, the question is: What am I doing wrong? Thanks in advance. Alex Pierry <http://pt.slideshare.net/marketingteclan> <http://blog.teclan.com.br/>

Can FS avoid sending re-INVITE to client? Or bridge on its behalf?
by M Yudkowsky 30 May '18

30 May '18

Comrades! I'd like to find out of if FS, which is making calls on behalf of a client, can intercept timer-based re-INVITEs and respond to them without sending the INVITE to the client first. Alternatively, can FS be made smart enough to bridge "in the cloud" on behalf a client, even if the client uses internal RTP port numbers? Details: I've got an internal server (IS) that uses FS as a firewall. The IS asks for leg A, then leg B, and then bridges leg A and leg B "in the cloud." FS (working in media bypass mode) handles this without any problems. For many non-NANP and some NANP calls, some SIP providers insist on a re-INVITE every 5 to 15 minutes. Unfortunately, the IS has a bug: if you send it a re-INVITE -- which is what FS does at this point -- the IS will respond correctly and continue the call in the cloud. But at the same time, the IS will open an internal RTP port (which is not used for anything) and then fail 60s later when no RTP reaches that port. At this point, the IS sends a BYE for one of the legs, requests the other leg back from the cloud, and continues to handle the remaining leg. Note that the IS in the course of normal processing does break the cloud conference, talk to each individual leg, bridges them together again or each with some other new leg... it's quite a dance of INVITEs and re-INVITEs that the IS sends. But inbound re-INVITEs related to timers is the problem at the moment. Two possible solutions: Solution A. Is there a way for FS to be made smart enough and aggressive enough to act on a routine, timer-related re-INVITE? If so, this would bypass the bug in our IS. Solution B. When FS is set to bypass RTP media, the bridge happens up in the cloud. In normal operating mode, without bypass or proxy of RTP set, this is what happens: When the IS attempts to bridge the calls it sends the bridging re-INVITEs to FS, and those re-INVITEs are for _internal_ ports that FS offered to the IS. FS bridges these internal ports but (and perhaps I'm reading Wireshark wrong) does not attempt to bridge the external ports and take the media into the cloud. The bridge is done on FS itself. A possible solution, then, would be to configure FS to determine that the media can be bridged in the cloud and have it do so. -- Moshe Yudkowsky Disaggregate Corporation 2952 W Fargo Chicago, IL 60645 USA +1 773 764 8727 speech(a)pobox.com http://www.Disaggregate.com http://www.PebbleAndAvalanche.com

No Resend 183 with Ring Groups
by Ximo Peral 30 May '18

30 May '18

Hi! I have a bridge with ring groups in the dialplan, using ":_:". When I receive 183 from my provider, FS does not resend. I'm "solving" this with ring_ready, but I do not like this option. Do you have any idea why the 183 does not propagate?

Call monitoring
by Francesco Facco de Lagarda 30 May '18

30 May '18

I am writing a "call monitor", something like an operator panel. I am capturing events via esl in php, filtering down the data and then sending them to a javascript UI via websocket. My problem is that I am totally bewildered by the amount of events that fs generates, and I'd like to filter it down to a bare minimum. New outgoing call (with uuid, extension and dialed number) Call answererd from other party Line busy Call hung up from either party. Can anyone give me a pointer to which events I really need to monitor, and which fields inside? I will obviously share finished code!
