[cisco-voip] Cisco ATA187 and Valcom 9940

[Jason Aarons (US)]

This is why I recommend FXO over FXS and not to use the Valcom 99XX. Stick with FXO and Valcom 200X.

Your problem is with (lack of) disconnect supervision, I was never able to fix it with SCCP ATA and CallManager.  Oddly the ATA supervisory disconnect behaves differently with CME/SCCP ATA.

Search the archives for my name and valcom or disconnect.

group,

I have an ATA187 with a Valcom 9940. When the caller makes a call to the 187, the Valcom answers and the page is made. When the ip phone caller hangs up the call, the 187 stays off hook. This results in a fast busy being played out over the Valcom 9940.

The behavior of an ata186 in the same setup is different. When the ip phone caller goes on-hook, so does the ata186.

I see some options on the ata187 to change, but some mild tweaking didn't change any behavior.

I am running ata187 load sip 9.0(3) with UCM 7.1(5b)SU2.

Any ideas?
