I have a customer who is changing from a TDM - ISDN30 service provider to a SIP trunk of 30 channels. They are using a 2851 with E1 modules at present running c2800nm-ipvoicek9-mz.124-11.T.bin. They have CM ver 4.1.(3).
My question is, should I advise them to first upgrade their present version of CUCM? Or, will they be able to use a SIP trunk from CM 4.1.3 and just add SIP config on their 2851 router. This router has 256/64 meg Dram/Flash and a PVDM2-48.
I don't want to be responsible for issues after the TDM to SIP change if they keep what they have and also would not want them to upgrade their CM just for this project if they can defer as this requirement is quite pressing.
I have a further question: could the customer reuse a 2851 router to connect to the Service Providers SIP trunk? I don't think CUBE is available for the 28xx routers, however, do they need CUBE? Or, could they just use SIP config on the router.
