[asterisk-users] CCM and multiple trunks

[Aaron Fransen]

I really have to learn to do more playing around before asking the group
these questions!

Here's the solution:

Create a second SIP Security Profile (but not on port 5061, since it's
reserved for secured connections...I used 5080).
Create a second trunk port using this second SIP security profile.

In Asterisk, you have to have two entries in sip.conf:

[callman01]
type=friend
context=incoming
host=x.x.x.x
disallow=all
allow=ulaw
allow=alaw
nat=yes
canreinvite=yes
qualify=yes

[callman02]
type=friend
context=incoming
host=x.x.x.x
disallow=all
allow=ulaw
allow=alaw
nat=yes
canreinvite=yes
qualify=yes
port=5080

They can both point to the same IP address.

Any needs more information just let me know.
