Jev,
 
You can use the pdt module to effectively define an area code for each SIP domain. pdt module will look for prefix no + code + termination no and then automatically append a domain stored in the database to the remaining number.
 
e.g. 5111012345@mydomain.com = 12345@otherdomain.com
and 5222012345@mydomain.com = 12345@anotherdomain.com
 
It does make the numbers a lot longer.. but if you want to be able to easily call other domains, i think it's a good way. The other alternative is to define particular prefixes, such as *15xxxxx@mydomain.com = xxxxx@otherdomain.com but i think this is a lot less elegant and requires hardcoding in the ser.cfg.
 
Hope this helps,
 
Dave

Subject: [Serusers] interdomain calls from numeric only UACs.

Hi All,

How do people deal with calls between virtual domains on the same ser
server from phones that can only easily dial numeric numbers and not
proper SIP uris?

Example,

two users,

2000@sipdomain1.com

calls

2000@sipdomain2.com ?

They are different users, as the domain distinguishes them, but for a
hard phone (like a analog phone connected to a ata, or a grandstream
phone) the user can only really _easily_ dial a simple number?

I'm sure this subject has been broached, it leads to the bigger question
of the usefulness of sip uris in context of traditional telephones? I
can think of effective ways around it by using prefixes and such, but I
want to hear about other peoples hopefully more elegant approach :)


Thanks,
-Jev
