Hello. I'm a new Asterisk user, but I'm impressed with the flexibility and versatility of Asterisk, and am moving quickly to adopt it's main-line use in our company. Hopefully, you'll be hearing more from me as the project moves forward. Right now, though, I have a question about SIP peer registration. Right now, for our SIP-based phone,s, we're using the Sip Express Router product, which accepts sip registration requests and lets us route calls to any of the phones which register with SER. I am a semi-nomatic user, and can work at any of three different locations. Right now, my phones all sign up with SER, and register with the same telephone number. When someone dials that number, all three phones ring, and which ever one gets answered first, gets the call. When I tried to do this with Asterisk, sources from the cvs repository as of 12/18/2003, sip show peers only showed the most recent registration. This lead me to believe that if I dialed the number, only the most recently registered phone would ring. I was able to work around the problem by defining an umbrella extension which rings all three phones at the same time, but I'd like to have a way of dynamically adding phones to a given extension without having to necessarily rewrite the extensions.conf file, and I'd like calls from these extensions to show up from the master extension that folks should use to reach me. I imagine I could do something with pickup groups, but my understanding is that it is not true that all phones in a pickup group will necessarily ring just because they're a member of a given pickup group. The phones on this particular extension are many miles from each other, so one couldn't hear the other phone ring. Another work around is to put Asterisk behind SER, but this seems overly complicated, and I want to make sure that Asterisk doesn't do what I want before I pursue that path.
Any suggestions on how to have multiple phones register with the same number in Asterisk?
In sip.conf:
[phone1] type=peer host=dynamic
[phone2] type=peer host=dynamic
[phone3] type=peer host=dynamic
in extensions.conf:
[default] exten => 0,1,Dial(SIP/phone1&SIP/phone2&SIP/phone3,30,T)
To explain further: Asterisk can only handle one client per peer definition in sip.conf. Multiple registrations per peer is not supported. Yet ;-)
SER support multiple destinations (a "destination set") per peer. SER is a SIP proxy, Asterisk is a PBX where a USER may have multiple extensions. Each extension - peer/client - have only one phone and the PBX dial plan takes care of dialling multiple destinations to reach a user, or a queue or .... anything's possible!
