Re: [SR-Users] Recommended configuration for TCP support

Thanks for your explanation, the problem is that the actual lookup is done by a proxy which is located after our load balancer. Therefore, the TCP connection with the UA should not be visible by the proxy but by the load balancer. How does that work in such case? *From:*sr-users [mailto:sr-users-bounces@lists.sip-router.org] *On Behalf Of *Vitaliy Aleksandrov *Sent:* Wednesday, May 06, 2015 10:34 AM *To:* sr-users(a)lists.sip-router.org *Subject:* Re: [SR-Users] Recommended configuration for TCP support *set_forward_no_connect()* called after lookup() prevents kamailio from making a new connection to a phone if there is no active connection. This is useful when you are trying to call to a UA which kamailio still keeps registration record for, but TCP/TLS connect to this phone is already gone (due to timeout, network problem, etc...).

What do you mean by not connect if there is no active connection after location lookup? *From:*sr-users [mailto:sr-users-bounces@lists.sip-router.org] *On Behalf Of *Daniel-Constantin Mierla *Sent:* Monday, May 04, 2015 11:07 PM *To:* Kamailio (SER) - Users Mailing List *Subject:* Re: [SR-Users] Recommended configuration for TCP support Hello, where are typically those issues with truncated SDP? On the phones? If you use tcp and have phones behind the nat, it is recommended to not connect if there is no active connection after location lookup -- see core functions for tcp.

What is the recommended configuration when TCP is used? Currently, I only have the following: children=16 listen=udp:<ip>:5060 listen=tcp:<ip>:5060 disable_tcp=no tcp_connection_lifetime=605 (registration expiry is 600) Also, is there a difference with UDP regarding NAT handling?
