Reaching VUC Via Junction Networks OnSIP
Generally when I join the weekly VUC conference all I’m dialed in from a SIP hard phone over a Junction Networks OnSIP trunk. This has historically meant that I had to dial in using the PSTN number, not the SIP URI.
A couple of times I tried to create an extension in my OnSIP account mapping their VUC SIP URI to a local four digit extension. That simply doesn’t work. The OnSIP GUI doesn’t permit the use of SIP URIs where the domain is specified by an IP address. It only accepts domains when referenced by alpha means.
