What I need to do is setup 4 Cisco IP Phones in a LAB to communicate with each other. They also need to be able to connect to POTS lines for outbound calls be it local or long distance. They will not have a BRI, PRI, SIP or T1 connected - their only source of outbound calling will be POTS. Also, the IP Phone(s) needs to ring when someone calls the POTS phone number.
Ive been looking at the UC520 - specifically the model UC520W-8U-4FXO-K9 which has integrated wireless.
Ive spoken with several pre-sales reps from Cisco and CDW and have received different answers. Some told me that this cant place calls over POTS lines while others told me that I could only place calls over POTS in a failover scenario if power is lost. 1 rep told me that this is exactly what I need to suit my needs as it comes with a VIC2 4FXO card.
Can anyone advise me if this is the best option? My main concern is that all IP Phones will be dialing out using POTS lines brought into a standard household analog telephone jack. All IP phones should be able to dial each other using internal extensions. Also, incoming calls to the POTS lines needs to be routed to the IP Phone(s) dpending on which number has been used.
This unit is a bit pricey but not outside of the budget. Im open to suggestions if there is another less expensive model tha will accomplish the same goals. There is currently a Cisco 8-Port 10/100/1000 Small Business Switch (SLM2008) and a Cisco ASA5505 10-User in the lab as well if any of those items will help in choosing a different piece of equipment.
Thanks for the help!
As a side note - I would also like to be able to setup Cisco Mobile on an iPhone to use the iPhone on the internal wireless network to place calls. I would also like to be able to setup SSL/VPN to connect the iPhone from an open wifi hotspot and make/receive calls. This is not as important but I would like the option of setting this up with the equipment that I choose. I was told that the UC520 does support that out of the box without any need to purchase extra software/hardware/licenses.
I would also like the ability to bring in a SIP trunk in the future. Im currently using a SIP trunk in the lab on an IP PBX that I may decide to start using with the Cisco equipment that I purchase.
