Solved: Is there any configuration changes required when switching to SIP trunks from PRIs

Garima Parghi · ‎10-03-2013

We currently have PRIs and now are moving to 2 SIP trunks. I have 2 2811 routers and using CUCM 8.6 upgrading soon to 9.x. I have been looking for notes on configuration changes required for the routers and/or Call manager but not able to find it. Any feedback/advise?

First, assuming you will have CUBEs in your environment you will need to ensure you build SIP trunks to the CUBEs in CUCM and point the Route Groups to these SIP trunks instead of the PRI GW (whatever protocol you used). Then, you will need to configure the CUBE, there are plenty of examples here and you can reference some good Cisco guides:
