trunk 3-digit PBXtra to 5-digit ShoreTel

[trevormarshall]

We have a ShoreTel 8 system at our HQ. We're acquiring a small company with a PBXtra box and I'd like to trunk the two together. I've successfully created a SIP trunk between the ShoreTel and a Trixbox so it should be ok.

Except - we use 5-digit dialing and they use 3, so when I try to create the off system extensions in the trunk group it tells me they must be 5 digits, as ours our.
Their 3-digit range does not conflict with ours so I would think this could work.

My options so far are:
1) change PBXtra from 3 digit to 5 digit. Problem is these people all have long-standing extensions on their business cards etc.
2) create route points in ShoreTel and use PSTN to 5-digit dial the PBXtra DIDS. Problem is most users do not have DIDs

Anyone know how to create a dialing rule to use the SIP trunk?

Cheers,
Trevor

Make them 5-digit off-system extensions, then set up a digit translation table on the trunk group.

Thanks! This appears to be working
I did 107xx -> 7xx
However, I'd like for everyone to use the 7xx extensions globally, so can I create another translation table for ShoreTel users? So we'd have
7xx (ShoreTel) -> 107xx (SIP Trunk) -> 7xx (PBXtra)

I'm not sure how you would do this. A custom dial plan may help, but I wouldn't know how to write it. The dial plan would translate 7xx to 107xx. Here's a hint: http://www.shoretelforums.com/forums...ial-codes.html
