I would need some help to find a DECT solution can work with Cisco Callmanager Express.
Which vendor / protocol can interoperate with cisco IP phones, if voice mail (CUE) can also work smoothly with the 3rd party DECT phones?
Any help is welcomed!
Thanks in advance!
DECT phone(s) ----radio link----base station(s)----SIP/H323/ISDN_trunk----CME---SCCP---cisco IP phones
If you use SIP, are you going to be looking to register your sip endpoint with CCME, or just pass SIP traffic/requests etc...to CCME? Cisco doesn't support any third party SIP phones on CCME, but it is possible to integrate third party phones...if you're looking to register them.
If you're looking to pass SIP traffic/requests to CCME then this is easy, you need inbound dial-peers for traffic from the base station and an outbound SIP dial-peer pointing traffic to the base station.
Also, H323 or ISDN could definately work as well, H323 is peer to peer protocol, just like SIP, so all you'd need is an inbound H323 dial-peer for inbound traffice to CCME or an outbound H323 dial-peer to point traffic to the phone.
ISDN would def. be possible as well, you'd need to use either a T1 VWIC card and configure it for ISDN/PRI or a BRI card...either will work, and the rest is just POTS dial-peer config.
We don't have any sort of specific docs for this, but if you let us know what you're looking to do, or how yo want to integrate...or more specifically, what the base station can do, let us know and we can figure someting out possibly.
Aastra makes a product like this.
I am sure there others, but this is one I remember hearing about.
