BCM 450 Network to another building utilize PRI and Vmail

[SNSSMIS]

We have a BCM450 in the main office and need 60 phones in another building that will have several fibers installed soon.
The current system is a 450 with 2 cabinets. 1 PRI, No analog trunks, 128 digital phones installed. No IP phones. Unlimited voicemail, call pilot clients. call center.
The PRI utilization is 50%.
The other building is a police atation and telephone system is currently IWATZU. It is reliable but needs replaced. Phones are failing. They have about 50 POTS that need ported over.
Does anyone have recomendations?

Put in another BCM450 with a PRI for porting over the pots lines.
Us SIP trunks to tie the two systems together.

Thanks for the reply, I was hoping to use the PRI already in place on main BCM450. Add a few POTS lines at the police department for backup. Will everyone in second 450 be able to use the voicemail and call pilot unified/voicemail/fax messaging?
I anticipated a unified system when the first BCM450 was installed.
A numbering plan was worked out with 4 digit extensions for each building.
What kind of codes will i need to purchase for the SIP? How many channels of voice do you get between systems? Non blocking?

You could always just go with all ip phones at the remote building as long as you have a connected network.

The number of sip channels would be up to the customers needs. Since it's all done over IP, a circuit between sites would have to be big enough to handle however many simultaneous calls they need.
Yes, they can use the first sites voice mail. I'm not quite sure why you'd want to do that. You get a voice mail system with each BCM. If the VoIP circuit between buildings went down, no voice mail. Put the license in at the PD and use that system.
You have buy a license for the number of SIP trunks you decide on.
If you use IP sets at the PD, you'd need those licenses. UM license if needed.
