Hello,
First, i have 7 years experience with Asterisk, but I started a project with Kamailio, forgive me in advance if I say silly things...! ;-)

I set up a classic Asterisk / Kamailio configuration:
sip phones -> kamailio -> asterisk -> sip trunks/pstn.

When a call comes from the PSTN side, if I configure Asterisk as follows:

[012345678]
type = friend
username = 012345678
secret = xxxxxxx
host = dynamic
fromdomain = sip.mydomain.com
fromuser = 012345678

Standard mode:
exten => 012345678, 1, Dial(SIP/012345678) -> The call is redirected on the phone by Kamailio ! :-)

------------------------------------------------------------------------------------------------------------------------------------------------


Trunk mode:

[mytrunk]
type = friend
username = mytrunkUser
secret = xxxxxxx
host = dynamic
fromdomain = sip.mydomain.com
fromuser = mytrunkUser


exten => 012345678, 1, Dial(SIP/mytrunk/012345678) -> The call is rejected by Kamailio....
exten => 012345679, 1, Dial(SIP/mytrunk/012345679) -> The call is rejected by Kamailio ....


My question is how to allow the routing of multiple numbers (trunk mode) in a SIP account with Kamailio?
Best regards,
Mickael
