mgcp gateway with cm 4.0

[rtdados]

I connect my pbx to a router 3825 using a NM-HDV2-E1. The router is working as a mgcp gateway to the CM 4.0. Now when i dial from a voip phone to the PBX i don't have the ring-back tone on the voip phone. If i dial from any telephone on the pbx it works fine. The conversation is working well on both ways. Can someone help me with the ring back tone problem?

Thanks.

[allan.thomas]

Do you have call progress tone configured on the voiceport on the gateway, cptone GB for example.

Could you kindly attach your configuration for review.

Try enabling the Setup non-ISDN Progress Indicator IE Enable on the CallManager MGCP gateway endpoint that connects to the PBX.

By default this setting is unchecked, this message message notifies the destination device that the CallManager gateway is non-ISDN and that the destination device should play in-band ringback.

This is usually attributed to problems with CallManagers connecting to PBXs through digital gateways.

Hope this helps.

Allan.

I tried but still doesn´t work.

[allan.thomas]

The following couple of line are evident on the pots dial-peer:

voice cut-through alert

tone ringback alert-no-PI

Have you specifically configured these entries, as these explicitly required for H225. H.225 is a protocol specified by H.323 for call signaling and call setup.

Progress tones are generated by the originating, terminating, or intermediate devices. The indication of in-band tones and announcements is controlled by the Progress Indicator (PI) information element (IE) in ISDN and H.323 networks.
