I hope these phone / asterisk compatibility questions are not considered OT for this list. I am currently in Grandstream hell and need a cost-effective way out :) Just wanted to know if anybody has experience with the Cisco 7905 / 7911 Running SIP with Asterisk. These seem like a good replacement for the GXP2000. My basic requirement at this point is a good IP phone that talks gsm/g729/ulaw and does not crash :) I have used the Cisco 7940G in the past without problems on Sip 8.1.X from cisco. Also it appears that Cisco does not support gsm as a codec. I'm assuming there are no grandstream-like problems with these cisco's. Cisco is much more co-operative than Linksys/Polycom and is working a feasible deal for me to replace GXPs with Cisco 7905/06G -- Faraz R Khan Chief Architect Emergen Consulting Pvt Ltd +92.21.111.111.320 x200 www.emergen.biz
