I have a scenario as follows.
A C3640 with
NM-2CE port0 is connected to telco
NM-2CE port1 is connected to company PBX
The PRI currently answers both data & modem calls.
I want to share the PRI so DID calls coming into E1-port0 can be redirected out E1-port1 towards the PBX - Also I need to be able to dial out from PBX into E1-port1 and the calls shall be redirected out E1-port0 to the telco.
Is this possible and do I need additional hardware?
- I also have a C2821 which I could plug the NM-30DM into but assume I need at least 2 E1 WIC's additionally, perhaps PVDM too?
- I do not need to terminate/originate calls to/from voIP.
doing q.931 debug I can see calls coming from PBX but the router has no idea on how to route them, and I am clueless how to if at all possible.
Atthachment contains circuit scenario.
thanks in advance.
I recognize your clarification, indeed I had missed you mentioning the 2821, still was no reason enough for a low rating.
Here the summary on your issue: it is not possible to process voice and modem calls with a single PRI interface (universal port) on either the 3640 or the ISR router. For that, only the AS5xxx are able to.
Consequently, on the router you will need a two-port VWIC or VWIC2 card; you will configure so certain DIDs are processed locally as voice or digital data calls, others are re-routed out the second port. There, you will cross-connect your data/modem box, be that a 2nd card in the same router, or on a separate one.
