Is the ringall feature supposed to work when dialing a sip number and another line using a Dahdi channel? I have had the ability use a ring-group or follow-me to have calls ring on my office phone and mobile, and it works fine as both phones ring until the timeout and music is heard on the calling parties end. I've always used a VOIP provider for the outbound call to my mobile so I never had the following problem. I've just set up a system for a client and was noticing that both ring-groups and follow-me would ring the internal sip extension once or twice, but then would stop a moment before the mobile phone started ringing. The outbound calls are going over a Dahdi channel. I checked this out back at my office and noticed the same thing once I switched the outbound route to a Dahdi channel. Two more things: 1) Once the internal extension stops ringing, the music on the calling parties end stops and you hear the mobile dialing. 2) When the call gets sent to the mobile, it never goes to the "destination if no answer" so if the mobile is not answered, the call will just go dead (asterisk won't send it to voice mail). It's like the system just hands it off to Dahdi and forgets about it. Using a VOIP provider to ring a mobile or other outside non-sip line, everything works. Is this expected behavior? Any way around this?
