I installed a SIP trunk yesterday, and wanted to follow best practices from the Cisco Live BRKUCC-3000 with regards to Dial-plan.
The Numbers are coming in from the Provider as +E.164, and wanted to add DN's with the same +E.164 pattern: +1xxxxxxxxxx,
But receive this error:
"Add failed. The first character cannot be a plus sign"
This sip trunk was the first step towards central SIP, and E.164 directly on the DN's...
