2 timeout 15 ephone-dn 33 dual-line number 133 no-reg primary label SIP-4333 call-forward busy 222 call-forward noan 222 timeout 15 But when the SIP INVITE comes in, it is looking for 9735554333 or 9735554222. How do I get the call sent to my new ephone-DNs? The answer lies in a feature called voice translations. With voice translations, I can translate any incoming or outgoing number in just about any way I want. Translation rules work like regular expressions. Here, I tell rule 1 within translation-rule 11 to replace any number with 133: R1-PBX(config)#voice translation-rule 11 R1-PBX(cfg-translation-rule)# rule 1 1.*/ /133/ Once the rule is created, we need to assign it to a voice translation-profile and name R1-PBX(config)#voice translation-profile SIP-Inbound R1-PBX(cfg-translation-profile)# translate called 11 Once that's done, we can assign our translation-profile to the incoming dial peer: R1-PBX(config)#dial-peer voice 89 voip R1-PBX(config-dial-peer)# translation-profile incoming SIP-Inbound Chapter VolP Remember when I said I'd broken MWI SIP dial peer? This translation is one of the reasons why. When the AIM-CUE dialed 8000101 to enable the MWI on my phone, it used SIP. The number matched the dial peer (.%) and was then translated to 133 because of this rule, which caused all the phones to ring. Now when I get an incoming call, it's routed to the phones that have ephone-DN 33 assigned to them. Here's the same call as before, but with the incoming translation applied: Feb 3 19:29:03.668: //-1/xxxxxxxxxxxx/SIP/Msg/ccsipDisplayMsg: Sent: SIP/2.0 100 Trying Via: SIP/2.0/UDP 208.73.146.95:5060;branch=z9hG4bK8v1qso00903gmpgqi501.1 From: "DONAHUE GARY " <sip:+19735551212@192.168.101.112:5060>;tag=gK025eb403 To: <sip:9735554333@192.168.101.100:5 Date: Thu, 03 Feb 2011 19:29:03 GMT Call-ID: pcst12967613435153831028210@192.168.201.112 CSeq: 1 INVITE Allow-Events: telephone-event Server: Cisco-SIPGateway/I0S-12.x Content-Length: 0 Feb 3 19:29:03.672: 1/-1/xxxxxxxxxxxx/SIP/Msg/ccsipDisplayMsg: Sent: SIP/2.0 180 R
