call forward on no answer
by frédéric Gaisnon 03 Jul '17

03 Jul '17

Hello, In my Platform i have a kamailio used as pseudo SBC and a kamailio used as Proxy (AS trigger) (cpl are applied on this instance). When I make a call and callee doesn't answer that call my SBC detects the timeout and generates a 408 to Proxy (according to fr_inv_timer) , but it generates CANCEL too. Is it possible to deactivate these CANCEL? if not what is the configuration in order to be able to trigger CFNA? Regards, Frédéric

evapi module and async_relay
by Diego Nadares 03 Jul '17

Hi guys, Anybody knows if evapi sends messages to the clients immediately when async_relay is called? The normal behavior is 1 or 2 netstrings per message but I see that sometimes it starts to enqueue and starts sending for example 4, 5, 15, 30, 52.....327, 645 per message. Cheers, Diego

remote ip address of sender and receiver
by vuleetu 03 Jul '17

03 Jul '17

Hi, all Is there any way to get remote ip address of both sender($si) and receiver(?)? I am configuring kamailio with multiple rtpproxy sets. Basically, rtpproxy set will be choosed based on the country those ip addresses of caller and callee belong to. Lets say if caller and callee are both in US, set 1 will selected. If they are not in the same country, set 2 will be selected. I dont know if there is any way to do that. Best regards Fisher

IOS 10 and SIP
by Kjeld Flarup 01 Jul '17

01 Jul '17

Rumours is that Apple no longer accepts apps which can do persistent connections in the background. To my best knowledge that means that IOS no longer supports SIP incoming calls. The app should now use Push Notifications, but SIP does not support this. Anybody faced this problem? Is the solution to call an external program when processing an Invite? This leaves some issues. 1. Should we wait some seconds before proceeding or wait until the Push notification has been processed, to give the app time to register. We cannot start to send invites, before we have a correct registration. An old registration may change ports when the app wakes up and makes a new register via NAT. 2. How do we know, if a given user should have a push notification? 3. Which information do we need to be able to send the push notification? 4. Does this give a penalty to Android users, because we have to wait for IOS? -- Med venlig hilsen / Best regards Kjeld Flarup (Christensen) M.Sc E.E, Teknisk chef Viptel ApS, Hammershusvej 16C, DK-7400 Herning Telefon: +45 46949949, Telefax: +45 46949950, http://viptel.dk
