Hello,
I am new to Issabel and VoIP systems. i have configured Issabel PBX and my sip is registered, extensions and outbound routes configured. i was having smooth operation of calling untill i converted the DHCP parameter to Static. The gateway and dns and host went blank which caused no internet to Issabel. I added the ip my router to Default Gateway 192.168.11.1 and DNS to my VMware ESXi host 192.168.11.10 whereas Issabel is running on 192.168.11.100 Static.. Now my Sip is fine and registered it can dial directly in softphone with credentials but i am unable to call via Issabel it gives 503 error. any help would be appreciated. i guess i am mistaking my with my dns or gateway probably.
