SIP-PRI plus FXS lines on Metaswitch

I can get a authenticated SIP binding to run a PRI and that works great (basic config below)

I can get a SIP trunk (no binding) to allow the FXS lines to individually register (basic config below)

but----the FXS  lines dont register on the authenticated binding for the PBX

or the FXS lines use PBX caller ID with unauthenticated binding

Ive seen others ask about combining these features but not specifically a scenario with Metaswitch.

+++++

PRI------simple and works

+++++

voice trunk T01 type sip

  sip-server primary x.x.x.x

  registrar primary x.x.x.x

  registrar threshold absolute 20

  dial-string source to

  codec-list TRUNK both

  authentication username "Adtran_Test" password "abcdefg"

!

voice trunk T02 type isdn

  resource-selection circular descending

  connect isdn-group 1

Re: SIP-PRI plus FXS lines on Metaswitch

Have the Metaswitch add the DIDs for the FXS lines to the registered trunk and just program them as voice users without individually registering. The TA900 will match the number of the voice user and route the call appropriately.

Re: SIP-PRI plus FXS lines on Metaswitch

I have not got back around to that little project but I'm sure you are right.

I may have stopped testing before finishing the matrix of possible configurations
