Has anyone successfully implemented concurrent appearance of the same PBX extension on multiple SIP phones? When using Cisco 7960s under call manager, you can have several phones with the same line appearance, but the first user to seize a line makes it inaccessible to other phones. Under SIP operation it seems as though this is not possible, but we don't see group ringing definable for SIP extensions. Thanks for your feedback Sam Zener

Also see bug 157. Hopefully this will be implemented in chan_sip2, this is bug nr. 759. What you can do is: Dial(technology/extension&technology2/extension2&technology3/extension3) or code it yourself (or put a money bounty on it). Kind regards, Geert

However, as you have described, this feature does work when using CCM. chan_skinny (and chan_sccp - which btw, will become the same channel driver soon) will eventually support this feature. If you (anyone?) have any motivation for Theo and myself to make Asterisk's SCCP support go to the top of our to-do lists, please contact either one of us off-list. Jeremy McNamara

Then you can build it as a Queue with the ringall feature.
