[cisco-voip] recommendations for handing off sip trunks as pri for legacy

[Mike]

Chris,

I've done this several times. You will need CUBE licenses and a multi-flex
T1 card (MFT), but you easily convert the SIP handoff to PRI.

Subject: [cisco-voip] recommendations for handing off sip trunks as pri for
legacy

We have recently acquired a new location which has a legacy analog pbx and a
carrier who was providing service as a PRI.

The carrier has now stated they will no longer be supporting PRI and are
recommending a switch to SIP trunks, which would be fine if they provided
adtran or similar to handle the conversion.

The carrier says they do not get involved in this situation and its up to
the customer, so we are left to fend for ourselves :)

This loction already has a 2851 with ipvoice, and I was thinking I should be
able to do everything I need with that?

Googling seems to turn up lots of configs which simply terminate local calls
to a physically connected PRI, when in actuality I want to do the inverse
and use the cisco to hand off a traditional PRI to the analog system.

Anyone gone down this path before? Have any config examples of what I
described that I can reference?

Also what type of linecard would I need to handoff the PRI? Does it need to
be a MFT T1 card or plain t1 dsu/csu?

thanks in advance
chris
