Re: [SR-Users] Create new listener on the fly

Hi Casrten, Thanks for the comment. I know you provide IMS, have you contributed to Kamailio IPsec, or do you have something in-house solution for this part? (I hope this question will not be off-topic) BR Hossein On Wednesday, October 26, 2022 at 06:37:33 AM PDT, Carsten Bock < carsten(a)ng-voice.com&gt; wrote: Hi Hossein, yes, you are right, it is in-efficient. It may be fine for a private network/PoC/Lab/ or anything else small, but it will not really work for a commercial network - for that you need something different.

This is the reason that the current ims_ipsec module will create a bunch of listeners at startup that looks not efficient.

Kamailio uses a static pool of preforked SIP worker processes, and this is initialised once upon startup. These child processes are spawned for every listener, and communicate and share data using SysV IPC and shared memory. The shared memory pool is likewise initialised upon startup, as is the small fixed-size area of private memory associated with each other worker process (“package memory”). While perhaps not strictly impossible to alter, this setup isn’t particularly amenable to the dynamic creation and destruction of listeners, or the additional child processes they beget. The child processes need to be forked on startup, before their heap is laden with runtime baggage. All this is relatively expensive to initialise. — Alex abalashov(a)evaristesys.com&gt; wrote: practical. wrote: know if there is any method to create a SIP listener on a specific port on the fly.
