Can I use the 3430 eSBC to change the codec of an outgoing INVITE based on the TN in the FROM header?

Jump to solution

I've got a PBX type that can't send different codec preferences based on individual telephone numbers.  This becomes a problem when I have to fax.  I want all other numbers on the PBX to INVITE with g729 first, but I want one or two fax numbers to INVITE with g711 only.  Can I do this with HMRs in the eSBC in the 3430?

The best way to handle this would be with SABR for outbound calls from the PBX and then to have two trunks inbound to the PBX and do normal routing inbound.

So, something like this, using 256-555-1212 and 256-555-1213 as the FAX numbers...

Note:  Eric and I determined that:

voice grouped-trunk PROVIDER-FAX

  trunk T02

  trunk T01

...

Should be:

voice grouped-trunk PROVIDER-FAX

  trunk T02

...
