Guys,
Currently unable to dial out to an external (non IPT platform) modem via our ATA 186.
We are currently running CUCM V 6.0 over an MGCP Gateway running IOS 12.4(16).
Modem is trying to negotiate but fails due to numerous connection errors - Modem has not answered at far end etc.
Any ideas.
Below is MGCP print.
mgcp dtmf-relay voip codec all mode out-of-band
mgcp rtp unreachable timeout 1000 action notify
mgcp modem passthrough voip mode nse
mgcp package-capability rtp-package
mgcp package-capability sst-package
mgcp package-capability pre-package
no mgcp package-capability res-package
no mgcp package-capability fxr-package
no mgcp timer receive-rtcp
mgcp sdp simple
mgcp rtp payload-type g726r16 static
!
mgcp profile default

Modems are not supported on ATAs. That doesn't mean that they won't work, but they're not supported. You could try lowering the speed to 9600.

Note: ATA 186 is not supported for analog modem calls. The modem referred to throughout the documentation implies fax modem.
