I have the following proposed design in mind for a customer:
OCS 2007-->Cisco 3800 series router for PSTN calls
Call Manager in a centralised topology with a voice gatway Cisco 2800 series at Customer A.
We would like to use a digital trunk between the Cisco 3800 series gateway and Cisco 2800 series router. Therefore calls to customers on the Customer B and other sites connected can be reached and treated as on-net calls.
Can you see any issues with this design? In particular the SIP conversion and also will there be a need for CUBE lic?
When you say digital trunk, do you mean PRI/QSIG connection between the routers?
Are the routers at the same location?
Or did you mean IP connection such as SIP trunk between the 2 routers? If so, you will obviously require IP routing between the 2 customers, you may be better off simply creating SIP trunk between OCS and CUCM directly which will not require CUBE licensing.
There is a Head office location which has a CUCM6 deployment. We would like to connect one of their branch location that has OCS installed as the PBX. The branch location has OCS PBX with a Cisco gateway to the PSTN. We have also deployed a Cisco 2800 router at the same site for sole purpose to connect to the 3800 router. We are thinking about using digital trunk with T1 PRI configuration. This design will not require ip routing between locations. Can you advise if this is a good design and if CUBE lic will needed.
