Frankly I have tired of the UC500 PBX config, bugs, complexities, and don't look forward to the BE series. So I have decided to swap a site from SCCP to SIP and have the phones talk directly to a virtual PBX provided by the ITSP (2talk.co.nz).
It is a fairly small site with only basic requirements for telephony, these days I would probably just use Yealink, Linksys or Snom phones if I were starting fresh. However I am hoping to not have to throw away the Cisco handsets which are quite nice, just the PBX.
My questions are
1. I understand I need to change the phones firmware to support SIP, is that a complex process? (many pot holes/bugs to be aware of)
2. Is the SIP firmware limited compared to a Yealink or Linksys phone? For example can I configure soft buttons to use custom feature codes?
3. Has anyone done this before that would be willing to share their experiences?
If its to hard then I will get rid of the lot as I am over the complexity and don't want the PBX as a single point of failure.
P.S> I have searched a bit, but have had no luck finding answers. I'm not even sure this is the correct forum to post too.
Cheers,
MC
