SA8507-H245 Support Wth Other Vendors

[WHCARon]

Can anyone provide me with the specification for this Green Feature. It appears under "system-parameters special-applications", but there is nothing in the documents.

This is all I've been able to get from Avaya.. ..

SA8507 - Support H245 DTMF Tones

Currently, R11.2 load 111 and earlier, when an MV is connected to a third party vendor H323 VOIP gateway, sometimes no DTMF tones were passed through from MV to the other vendors and vice versa. Vendors like CISCO and Clarent are known to have this problem when they interop with MV.

In H323 standard, DTMF tones are passed via the H245 link. When MV connects with vendors like CISCO or Clarent, neither side of the call tried to bring up the H245 channel and no H245 channels were established, thus no DTMF were passed through. Between MV and MV, this was not a problem. MV has its own proprietary way of passing DTMF tones. This problem is only seen when other vendors support FastStart call setup procedure, which is a procedure to setup call without establishing the H245 link.

3.4. Configuring Avaya Communication Manager For Out-Of-Band DTMF Relay via H245
Cisco GWs only support out-of-band DTMF via an H.245 message. Avaya Communication Manager supports DTMF relay via H245-signal and H245-alphanumeric from Cisco. The Avaya S8500 Media Server must be configured to send out-of-band DTMF via H.245. Use the command display system-parameters special-applications to verify that H245 Support With Other Vendors is set to y. In addition, DTMF over IP must be configured to out-of-band on the signaling groups
