Hey guys,
Recently we are facing an issue where Sip Server starts to getting a sip 480 - Temporarily Not Available like this:
SIP/2.0 480 Temporarily Unavailable
Via: SIP/2.0/UDP XXX.XXX.132.158:5060;branch=z9hG4bK65DB48BF-E008-4FAA-8B6F-C5AE77D0978C-105915356

Warning: 399 XXX.XXX.132.135 “Insufficient source resource port capacity”
132.158 is SIP VIP and 132.135 is RM.
The outbound trunks capacity is below the limit.
To solve this, we have to restart RM and we have having to do that like 3x a week.
I tried to look at some guides and the closest thing i found so far is that Genesys recommends not to use many trunk groups due to excess of subscription ids.
Anyone knows why is this happening ?
