PJSip CallerID Question

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” ?

  • So how did you do that?

    You examples contradict.

    TIMTOWTDI, but I’d choose to set the CALLERID(name) on the sending side dialplan (where it routes calls to external extensions).

  • Uhh, I actually don’t remember, and I didn’t save any of the old config when I upgraded the servers.  Yeah, I know. 
    Yeah, that was a type.  Should read:

    The Desired configuration is for Extension 20 to show “Location A – 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.

    that section of the dialplan over during the upgrade.  Probably because I wanted to get incoming calls working at all locations first, then tackle office to office later.

    Thanks.
