[asterisk-users] callerid not working over sip

[sean darcy]

Calling from my home using Asterisk 1.6.2.1 to an office extension 
(Asterisk 1.6.1.13) the callerid is not honored:

Home:

     -- Starting simple switch on 'DAHDI/1-1'
     -- Executing [170 at internal:1] Answer("DAHDI/1-1", "") in new stack
     -- Executing [170 at internal:2] NoOp("DAHDI/1-1", "Context: 
office-extensions") in new stack
     -- Executing [170 at internal:3] Set("DAHDI/1-1", "CALLERID="Test" 
<447>") in new stack
     -- Executing [170 at internal:4] Dial("DAHDI/1-1", 
"SIP/office-home-sip/170") in new stack
   == Using SIP RTP TOS bits 184
   == Using SIP RTP CoS mark 5
   == Using SIP VRTP TOS bits 136
   == Using SIP VRTP CoS mark 4
   == Using UDPTL TOS bits 184
   == Using UDPTL CoS mark 5
     -- Called office-home-sip/170


On the office asterisk:

  == Using SIP RTP TOS bits 184
   == Using SIP RTP CoS mark 5
   == Using SIP VRTP CoS mark 6
   == Using UDPTL TOS bits 184
   == Using UDPTL CoS mark 5
     -- Executing [170 at default:1] Macro("SIP/xxx.yyy.zzz.aaa-00000176", 
"stdexten,170,SIP/170") in new stack
     -- Executing [s at macro-stdexten:1] 
NoOp("SIP/xxx.yyy.zzz.aaa-00000176", ""CallerID is: ""asterisk" 
<asterisk>") in new stack
     -- Executing [s at macro-stdexten:2] 
Dial("SIP/xxx.yyy.zzz.aaa-00000176", "SIP/170,18,rtT") in new stack
   == Using SIP RTP TOS bits 184
   == Using SIP RTP CoS mark 5
   == Using SIP VRTP CoS mark 6
   == Using UDPTL TOS bits 184
   == Using UDPTL CoS mark 5
     -- Called 170

Why isn't the office asterisk picking up the callerid from the home 
asterisk?
