Hi Segriu
I think my issue is with rtpengine . I’m using direction parameter to set a LAN and WAN IP on the offer and I think it’s getting messed up during re-invites Best Regards Gerry Kernan From: sr-users [mailto:sr-users-boun...@lists.kamailio.org] On Behalf Of Sergiu Pojoga Sent: 23 March 2018 01:34 To: Kamailio (SER) - Users Mailing List <sr-users@lists.kamailio.org> Subject: <UNJUNKED> Re: [SR-Users] Audio stops after resuming call from hold OMG, what are the odds, a client reported the same problem today! Edge proxy running same 4.2.3, requests are forwarded to a farm of Asterisks v13 in a similar way based on $rd, far-end NAT traversal is handled by Kamailio. I've had only an hour or so to debug today. Re-invites containing SDP are handled the same way as invites in terms of SDP mangling, all looks good in that sense. There's nothing special to be done about re-invites. Preliminary clue is that this happens (or not) depending on the type of firewall/NAT behind which the phone is located. In the case with the trouble, it's a Sonicwall, probably a Symmetric NAT. Is doesn't happen to a phone behind a Full/Restricted Cone NAT. What nat= are you setting for Asterisk peers? Do you engage rtpproxy/rtpengine? Any far-end NAT traversal manipulations involved such as SIP ALG or STUN? Cheers.

I have a Kamailio Ver: 4.2.3-1.1 running in front of a few asterisk servers Ver: 13.17.2 sip is routed to an asterisk server depending the domain name in the sip request, all working as expected . but if a call is put on hold after resuming the call the party that placed the call on hold can’t hear any audio. The other party can hear . do I need to do anything special to handle re-invites for calls put on hold?
