Edit calling numbers only when 911 is dialed

A customer has several sites whose SIP traffic passes through an Adtran SBC and they need to edit the calling number only when 911 is called.  When not calling 911, the number should not be altered.  The challenge is that depending on the site, the number will need to be different.  For example:

SiteCalling NumberReplacement Number only for 911

A

B

C

D

111-111-1111

222-222-2222

333-333-3333

444-444-4444

111-111-5555

222-222-6666

333-333-7777

444-444-8888

Is there a way with ANI / DNIS substitution to first match when a 911 call is made and then make the substitution based on the calling number?

Re: Edit calling numbers only when 911 is dialed

Are there four SBCs, one at each site, or one for all four sites? If there is one at each site, the command:

caller-id-override emergency-outbound 1111115555

applied to the trunk facing the PSTN will do the trick

Re: Edit calling numbers only when 911 is dialed

There is only one central SBC for all sites, so that doesn't sound like it will work.   I never knew about that command before, so thank you for sharing.
