My SIP trunk provider has a large range of IP’s they need me to accept traffic from. However I cannot add the complete list on the Trunk Match field and save it. It just errors reporting SQL statement is to long. Is there a work around for this ?
It seems all these IPs are media IPs and you just need to configure with SIP IP/ URI which is sip.prod.gradwell.com
And In firewall you may allow RTP port 10000 to 20000 for any IP to any IP
