Howdy all, I have recently added a SPA525G2 to our existing Mitel 5000 CP. Let me start off with the comment that this is very nearly a perfect IP phone. If it had a gigabit switch instead of 10/100 it would get there I have it working on the Mitel switch -- I can make/receive calls, get voice mail indications, etc... I have only one feature that's giving me fits -- Attended Transfer. On the Mitel we have two options for performing transfers -- Transfer to Ring (3345) and Transfer to Hold (3346). I use the *3345 for blind transfer, and it works exactly as expected. However, for the attended transfer, I have yet to get it to work right -- I cannot transfer the call after the user picks up... it only tells me that the transfer failed, and then I cannot get back to the calls. Troubleshooting settings I have played with: SIP - Hold Target Before Refer, Keep Referee when REFER Failed SIP - NAT SUpport - Handle VIA, Insert VIA Regional - Referral Services Codes (*3345) Extension - Blind Attn-Xfer Enable

Good Morning all! I have several small branch offices with 2 to 10 users. I'd rebuilt the systems about three years ago with Cisco 1811W's, but now they are going end-of-life. As I search Cisco's sites, I came across the new SRP-541W (http://www.cisco.com/en/US/prod/collateral/voicesw/ps6790/gatecont/ps10500/data_sheet_c78-550705.html) It seems almost perfect.... with only one drawback. I can't do DMVPN any more, a feature I truly came to consider the pinnacle of Cisco's commitment to the SMB space -- I mean a VPN where you only have to know with Hub IP -- that would dynamically create spoke connections... Read more about DMVPN here (http://www.cisco.com/en/US/products/ps6658/index.htmlhttp://www.cisco.com/en/US/products/ps6658/index.html ) I am reading about the GRE tunneling feature (which has one part of the equation -- the ability to make a nice tunnel) and the IPSEC point-to-point... but it does not seem that they'd really play nice with the hub/spoke scenario, where I could drop one of these routers behind nearly anything (DSL, leased-space network, Phone company services, etc...) and have the tunnel dynamically connect. Maybe I'm just reading it wrong. Do any of you out there have experience with the the 520 or 541 connecting back to a hub-site, when you only know the hub IP address (and only want to care about that one?) If it really isn't there, then consider this a strong request to add DMVPN to the 540 series.
