Kamailio - FreeSWITCH - RTPproxy
by Jerry Kendall 20 Sep '21

20 Sep '21

Hello all, I am new to the list but have been reading plenty. Loads of good tips and help. I am playing with Freeswitch and would like to put Kamailio/RTPProxy in front for the user endpoints. Freeswitch will talk directly with the service provider. I am wondering *if* i can do this... 1) have the endpoints register with kamailio 2) have the media proxy via RTPProxy as it is needed for NAT 3) have the actual work (voicemail/ring groups/ivr/conference/etc...) done on Freeswitch 4) have all the SUBSCRIBE/PUBLISH/PRESENCE done on Kamailio Is this doable? Are there any guides to setting this sort of thing up? regards, Jerry

Reinite breaks the call
by Angelo Sipper 20 Sep '21

20 Sep '21

Hello, I am trying to understand a problem we have with reinvites. When there is a reinvite on the call our provider refuses to receive the reinvite and the call is dropped. The setup is the bellow: UA-> Kamailio1 -> Kamailio2 -> Provider On Kamailio2 we have Topos enabled. Looking on the trace I can see that on the second invite, Kamailio does send out the original contact and not the one that was originally send out to the provider. Is this correct? Is this breaking the call? Bellow the trace and the flow from Kamailio2 until the second reinvite. All reinvites are the same as per the last Thank you for your help! 2021/09/15 16:29:59.420162 50.50.50.181:5060 -> 200.200.200.193:5060 INVITE sip:1234567890@sip.mydomain.com:5060 SIP/2.0 Via:

Thanks Mojtaba, problem was solved. I performed LRKProxy first, then Kamailio.

BLF when phone boots up
by Jerry Kendall 17 Sep '21

17 Sep '21

Hi, I have looked at lots of postings but can't seem to find the answer I seek. I have 6 phones (Grandstream GXP2170, etc) connected to Kamailio 5.2.1 running default config file with changes per https://kb.asipto.com/kamailio:presence:k43-blf On x301, I have the 3 BLFs setup to monitor x302, x303 and x304. If I dial 303 from 301, the BLFs work (flash, red, then green) as expected. But, when the phone initially boots up, the BLFs are all dead - until the first PUBLISH event. So, the question is, how do I get the BLFs to become valid and with the correct status when the phone boots up??? regards, Jerry

listen directive during runtime
by Tihomir Culjaga 17 Sep '21

Hi, is it possible to add a listen directive during kamailio runtime ? The reason I'm asking this is in a situation when I add a new peering trunk (from a different network segment), I need to add a network interface to the kamailio server and then add a specific listen directive for that interface to reference the socket by name. listen=udp:10.1.1.11 name "mySN1" so i can further reference to a specific socket name when routing SIP messages. Please advise, Regards, Tihomir.

I don't think you understood. The issue is in v5.2.5, and I tried to update kamailio but it still remains. I honestly think this is a machine problem, since I can't even send the notifications to 0.0.0.0:5090. It is very weird. Best Regards, José Santos
