Hi All, I am doing the call from the A Endpoint to B Endpoint using FreeSwitch In Between When FreeSwitch Get the INVITE Request from the A Endpoint, I am using the following absolute_codec_string. absolute_codec_string = "PCMU,PCMA,G726-40,G726-32,G726-24,G726-16,G729,GSM,L16,ILBC,G723" FreeSwitch is also sending the INVITE Request to B Leg with the codecs defining in the absolute_codec_string. Which is as below. 592f8a31-4978-1233-90b2-d4ae52cde95f] send 1291 bytes to udp/[192.168.14.68]:5060 at 07:48:32.929086: ------------------------------------------------------------------------ [592f8a31-4978-1233-90b2-d4ae52cde95f] INVITE sip:12191121212@192.168.14.68:5060 SIP/2.0 [592f8a31-4978-1233-90b2-d4ae52cde95f] Via: SIP/2.0/UDP 192.168.2.165;rport;branch=z9hG4bK4mtN7XDy2Xg7B [592f8a31-4978-1233-90b2-d4ae52cde95f] Max-Forwards: 68 [592f8a31-4978-1233-90b2-d4ae52cde95f] From: "dhrupla" <sip:14191121212@192.168.2.165>;tag=4cHc3S7N80tpm [592f8a31-4978-1233-90b2-d4ae52cde95f] To: <sip:12191121212@192.168.14.68:5060> [592f8a31-4978-1233-90b2-d4ae52cde95f] Call-ID: 592f8a31-4978-1233-90b2-d4ae52cde95f [592f8a31-4978-1233-90b2-d4ae52cde95f] CSeq: 73082792 INVITE [592f8a31-4978-1233-90b2-d4ae52cde95f] Contact: <sip:iMAX_SS@192.168.2.165:5060> [592f8a31-4978-1233-90b2-d4ae52cde95f] User-Agent: iMax_SS [592f8a31-4978-1233-90b2-d4ae52cde95f] Allow: INVITE, ACK, BYE, CANCEL, OPTIONS, MESSAGE, INFO, UPDATE, REGISTER, REFER, NOTIFY [592f8a31-4978-1233-90b2-d4ae52cde95f] Supported: precondition, path, replaces [592f8a31-4978-1233-90b2-d4ae52cde95f] Allow-Events: talk, hold, conference, refer [592f8a31-4978-1233-90b2-d4ae52cde95f] Content-Type: application/sdp [592f8a31-4978-1233-90b2-d4ae52cde95f] Content-Disposition: session [592f8a31-4978-1233-90b2-d4ae52cde95f] Content-Length: 653 [592f8a31-4978-1233-90b2-d4ae52cde95f] v=0 [592f8a31-4978-1233-90b2-d4ae52cde95f] o=iMax_SS 1426824519 1426824521 IN IP4 192.168.2.165 [592f8a31-4978-1233-90b2-d4ae52cde95f] s=iMax_SS [592f8a31-4978-1233-90b2-d4ae52cde95f] c=IN IP4 192.168.2.212 [592f8a31-4978-1233-90b2-d4ae52cde95f] t=0 0 [592f8a31-4978-1233-90b2-d4ae52cde95f] m=audio 13193 RTP/AVP 0 8 98 99 100 102 18 3 103 104 101 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=rtpmap:0 PCMU/8000 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=rtpmap:8 PCMA/8000 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=rtpmap:98 G726-40/8000 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=rtpmap:99 G726-32/8000 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=rtpmap:100 G726-24/8000 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=rtpmap:102 G726-16/8000 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=rtpmap:18 G729/8000 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=rtpmap:3 GSM/8000 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=rtpmap:103 L16/8000 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=rtpmap:104 iLBC/8000 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=fmtp:104 mode=30 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=rtpmap:101 telephone-event/8000 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=fmtp:101 0-16 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=silenceSupp:off - - - - [592f8a31-4978-1233-90b2-d4ae52cde95f] a=ptime:20 [592f8a31-4978-1233-90b2-d4ae52cde95f] m=audio 13193 RTP/AVP 4 101 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=rtpmap:4 G723/8000 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=rtpmap:101 telephone-event/8000 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=fmtp:101 0-16 [592f8a31-4978-1233-90b2-d4ae52cde95f] a=silenceSupp:off - - - - [592f8a31-4978-1233-90b2-d4ae52cde95f] a=ptime:30 But Here Strange Behaviour is with G723 Codec.

Bare Minimum Freeswitch
by Jacob Hodges 09 Mar '15

09 Mar '15

Hi all, I'm quite new to freeswitch and have used it in the past to establish a SIP Trunk between Lync and another SIP provider. I'm now looking at Freeswitch as a potential replacement for a legacy PBX at my local church. I'm extremely wary of the default Freeswitch configuration as it seem to include a lot of functionality that I don't need and a lot configuration I don't understand. All I need is the following: - 5 extensions that can dial each other and the PSTN - Ability to do group pickup, paging and voicemail to email - Ability to set day/night mode - Ability to use SPA3102 as a gateway to the PSTN. Can anyone tell me the minimum number of modules / configuration that is needed to accomplish this? Thanks, Jacob.

mod_rayo patching
by ik 08 Mar '15

08 Mar '15

Hello, There is a bug in mod_rayo that I wish to patch myself, however I have never touched any sources of FS before, not to mention rayo itself (and it's been many years since I touched C). Before I'll start to figure out the proper source code to touch, is there a good guide to read about FS development that can help in the matter ? Thanks Ido

valet parking new feature
by e schmidbauer 19 Feb '15

19 Feb '15

Hi, Would anyone want to test out new parking feature for polycoms? The feature is outlined in this doc: http://support.polycom.com/global/documents/support/technical/products/voic… Just pull clean FS branch and do a git apply with that diff like git apply --ignore-whitespace ~/valet_sofia.c.diff make mod_sofia-install make mod_valet_parking-install restart FS Provisiong the polycom with: attendant.resourceList.2.address="orbit+lot(a)mydomain.com" attendant.resourceList.2.label="Orbit Lot" attendant.resourceList.2.type="automata" FreeSWITCH dialplan Park in Orbit: <extension name="parking_auto_in"> <condition field="destination_number" expression="^\*7$"> <action application="answer"/> <action application="valet_park" data="lot(a)mydomain.com auto in 701 799"/> </condition> </extension> Pick up from Orbit: <extension name="parking_pickup"> <condition field="destination_number" expression="^\*97(7[0-9][1-9])$"> <action application="answer"/> <action application="valet_park" data="lot(a)mydomain.com $1"/> </condition> </extension> Please test and let me know what you think... I'd like to get this feature pushed to valet_parking instead of forking the module Thanks
