Configure ATA for hotdial

Is it possible to perform hotdial with ATA and analog phones?

Re: Configure ATA for hotdial

I've got ATA 188 (ATA188-I1-A) with software version v3.1.1 atasccp (Build 040610A). This information is from ATA configuration WEB page.

But on ATA configuration page I can't see parameters close to dialpan.

I consider, that parameter DialPlan=H0 can be set only if SIP software is installed into ATA.

Am I right?

This is done with the H323 image on the ATA.

Re: Configure ATA for hotdial


As I understood from your reply and Cisco documentation I can perform hotdial with ATA in 2 cases.

1) ATA SIP image. Disadvantage - I need to install SIP proxy. Because my CallManager 4.1 doesn't fully support SIP

2) ATA H323 image. Disadvantage - I need router/software based H232 gatekeeper. Also H323 ATA image is EoS.

OK. Now I have yet another question.

Can 2851 with IOS 12.4(4)T Advanced IP services acts as a SIP proxy?
