[Freeswitch-dev] Consultancy?
by Andy Newlands 29 Jun '20

29 Jun '20

We are using Freeswitch as the core of our UK-based SIP platform, which connects with main carriers in the UK, and have a couple of issues which we have been unable to properly resolve ourselves. We are now seeking a Freeswitch expert who can assist in achieving resolution, on a consultancy/contract basis. Where is the most appropriate place to find suitably qualified experts, with proven track-records and endorsements? Layout is basically PSTN_CARRIER<->FS<-->CUSTOMER_PBX (there are also proxies and FS-based SBCs (Kamailio)) At high-level, the issues are: - Loss of RTP when a call is transferred or diverted by the CUSTOMER_PBX - Attempting to transfer a call from the CUSTOMER_PBX can result in ringback continuing, after the transfer-to endpoint answers (again, no RTP). - Behaviour varies depending on which PSTN_CARRIER calls are routed through (we have multiple interconnects) - We can see nothing obviously wrong in the call traces. Thank you Kind regards, Andy

[Freeswitch-dev] ADD 2 ICE CANDIDATES mod_verto
by Jazmin Marina Florez Marino 02 Jun '20

02 Jun '20

Hello all, I am working with mod_verto in a scenario where I need to send public and private IP addresses as ICE candidates. When I modify the ext-rtp-ip parameter, it only sends one option as typ host ice candidate. However, for my implementation I need to send both. What I need is the combination of those ice candidates, something like this: a=candidate:8228103366 1 udp 659136 190.84.118.88 31028 typ host generation 0 a=candidate:3496438569 1 udp 659136 192.168.1.170 24210 typ host generation 0 Is it possible to add both ice candidates in the same SDP from configuration files?
