I have no concerns regarding this. IMO the additional load does not really hurt small systems - and large systems should already be designed to scale out ;-) Seriously: the only reason for "pings" is keeping "UDP connections" (even if there is no such thing) alive. Most systems that require such things need traffic from "inside" - so UDP ping is mostly pretty useless, trash it! >> No extra function is needed, just some extra avps. > makes sense - if there are not so many vals to push. In my initial feature request I mentioned keepalive_interval_avp and keepalive_method_avp - while the naming could be subject to discussions those should be the only two required AVPs to satisfy the proposed enhancements. It seems that we agree on the interval-part - this would allow to use a not-so-frequent default interval (saving ressources) and grant the option to make it more "aggressive" for users having issues with the default setting. As you asked for real-world example for the "per-user-ping-type" feature request: while preparing our new VoIP platform I've switched to nat_traversal and configured NOTIFY, as it seemed to be the more elegant variant. This went well, unless I've met problems with some UACs (tested AVM, Snom, Grandsteam - don't remember which one had the problem) behind an enterprise firewall (Nokia Checkpoint or Juniper Netscreen, both cluster installations - don't remember even here which one it has been). There have no longer been no replies to my NOTIFY, I switched to OPTIONS and it worked. I must confess that I didn't try to find out who caused the problem (ALG or UAC) - I've just seen issues with NOTIFY and opted for the second option (OPTIONS). Nonetheless I would welcome the possibility to switch back to NOTIFY and use OPTIONS just where I encounter problems.
