I have a Sangoma Vega 200G ISDN-SIP Gateway connected to PBXact with a SIP trunk and the caller’s telephone number is missing the leading zero. There are many very similar posts about this issue but none have an actual step by step fix.
From the other posts it looks like I need to get the inbound trunk to go through a custom dialplan prepend a zero if necessary but none of the replies actually say how to do this. If this is the only approach then can you please tell me:
- How do I direct a trunk to a custom configuration from Modules->Trunks->MYTRUNKNAME
- How do I create a custom dialplan to prepend the zero if it’s missing? I can see examples of dialplan script in the forum but not where I actually type this in the PBXAct web GUI.
I have PBXact v188.8.131.52.
