As an example, entering the following value in the field:
^(1\d{3}555210\d)$
Would match the sequence
“1xxx555210x”
where
“x”
is any digit.
confIgurIng for a Pbx
In the case where you wish to set up incoming lines as extensions of an upstream PBX, the instructions are very
similar. Your PBX will deliver channels to VH2 in the same way a SIP provider does, and you will need to set up the
PBX and retrieve the proper credentials to program into the
SIP Provider
fields
in VH2. IP PBX programming is usually very complex and is usually handled by the PBX vendor. Inform the vendor
that you wish to set up an extension with “
x
” number of simultaneous channels and without additional features like
conferencing, transfer, etc. (since VH2 doesn’t support these functions).
gateWays
Gateways allow you to use VH2 with traditional analog phone lines, as well as T1, BRI and PRI ISDN, and other
legacy telephone trunks. Gateways will convert these telephone channels to SIP-style virtual phone lines. You will
need to find gateways that deliver FXO style channels on their telco side - the ports on the gateway are designed to
point toward the telephone service (and not interface with telephones and PBXs, like an FXS port does).
Setup of gateway devices can be quite complex. Comrex maintains some basic instructions on how to set the
gateways we prefer on our website.

Gateways deliver their virtual SIP lines differently than SIP providers. With gateways, VH2 becomes the “provider”
and the gateways register with it. This means the credentials you set up on VH2 will be generated by you, and they
will need to be mirrored into the gateway. To use a gateway, both the gateway and the VH2 must have Static IP
addresses so they can find each other.
