[asterisk-users] PJSip CallerID Question

[Brent Davidson]

I have multiple Asterisk instances set up in different locations and 
would like to modify the callerID of inbound calls to identify which 
instance the call is coming from.  I knew how to do that with the old 
sip format, but can't seem to figure it out with PJSip.

For example:

Currently Location A, extension 10 calls Location B, extension 20.  
CallerID on Extension 20 displays "10" for the callerID.

The Desired configuration is for Extension 20 to show "Locati0n B - 10" 
on the caller ID.  I don't want to modify the caller ID for each 
individual extension as I want the intra-location caller IDs to show 
just the extension number.  (e.g. LocA/Ext. 10 calls LocA/Ext11 - 
LocA/Ext11's CallerID displays "10", but LocA/Ext10 calling LocB/Ext20 
displays "Location A - 10" for caller ID.

I have my locations set up in the pjsip_wizard.conf file like this:

Location A:

[Uplink_defaults](!)
type = wizard
transport = transport-udp
endpoint/allow_subscribe = no
endpoint/allow = !all,g729
aor/qualify_frequency = 30
registration/expiration = 1800

[Location B](Uplink_defaults)
endpoint/context = internal
remote_hosts = 10.10.20.253:5060
sends_registrations = no
accepts_registrations = no
sends_auth = no
accepts_auth = no

Location B:

[Uplink_defaults](!)
type = wizard
transport = transport-udp
endpoint/allow_subscribe = no
endpoint/allow = !all,g729
aor/qualify_frequency = 30
registration/expiration = 1800

[Location A](Uplink_defaults)
endpoint/context = internal
remote_hosts = 10.10.11.5:5060
sends_registrations = no
accepts_registrations = no
sends_auth = no
accepts_auth = no

Rather than routing these to the "internal" context, should I create 
another context and somehow parse/manipulate the caller ID in there then 
route to "internal" ?
