Description

Having 2 clients (Groundwire, Snom 370) registering on a shared sip2sip account behind a multi-WAN router, resulting in:
  1. 10 registered contacts
  2. SIP/2.0 500 Service Unavailable error
  3. P-Registrar-Error: Too many registered contacts

This should be taken care of on the server side. For example, it should be able to compare the rinstance and replace old ones with the new ones.

The Snom contact registration is only once, and therefore declared ok:

<sip:2233513173@192.168.254.10:1061;transport=tls;line=391tpzbw>;q=1;expires=31556;received="sip:92.254.51.247:1061;transport=tls",

The 3G/UMTS/mobile link registration:

<sips:2233513173@10.46.160.173:58629;rinstance=7DA4013B;transport=tcp>;expires=60133;received="sip:188.207.108.46:32424;transport=tls",
<sips:2233513173@10.46.160.173:58620;rinstance=7DA4013B;transport=tcp>;expires=59370;received="sip:188.207.108.46:32408;transport=tls",

should already be removed from its oldest registration (lowest expires) in my opinion.

The 3 registered contacts for Wi-Fi WAN link #1:

<sips:2233513173@192.168.254.12:58832;rinstance=7DA4013B;transport=tcp>;expires=84070;received="sip:92.254.51.247:58832;transport=tls",

should also be removed from its oldest registrations (lowest expires values) in my opinion.

And the 4 registrations for Wi-Fi WAN link number 2:

<sips:2233513173@192.168.254.12:58658;rinstance=7DA4013B;transport=tcp>;expires=61191;received="sip:81.23.228.129:5060;target=%73%69%70:%37%37.%31%37%33.%31%38%35.%34%34:%35%38%36%35%38%3b%74%72%61%6e%73%70%6f%72%74%3d%74%6c%73",

may also be de-duped and registered without target "sip:77.173.185.44:58658;transport=tls".
