Is there anyone here willing and able to offer a current configuration guide for using twilio SIP Trunks with the current UCM6510 (firmware ver 220.127.116.11). I’ve been working on this new setup for a day and a half with no success.
I’ve scoured the net for information, referenced twilio’s outdated guide, etc with no success. I’ve found little info for matching twilio’s SIP Trunk settings with the current Grandstream interface.
I’m not locked into twilio’s SIP service and open to looking at other top quality SIP Trunk providers.
