Thans a lot.

Hi, the "h245-alphanumeric" is an H.323 protocol and you cannot use this with SIP.

It's not supported. Leave only "dtmf-relay rtp-nte" in your config.

With this option your gateway will negotiate RDC2833 DTMF relay method.

What method is supported by your 3PTY gateway?

You can also test SIP INFO using "dtmf-relay sip-notify" options.

If you use not compressed codec (g.711 only) you can remove the option "dtmf-relay" and test dtmf in band method. In this case the DTMF tones are sent as voice directly to your PSTN line.

Regards.

Hi, Thanks your reply.

I already test all option.

But I didn't success this issue.

I can hear tone from remote pstn but I can not send extra button for remote local call.

This is a exact problem.

Thanks a lot.

[Daniele Giordano]

Can you kindly add the output of "debuc ccsip message" from the 2911?

I want check the DTMF method negotiated from the third party gateway, your router and the SIP phone.

Thanks.

Hi,

RTP-NTE isn't supported in CFB (hardware or software).

Change this to another SIP method such as SIP-NOTIFY or SIP-KPML.

The h323 command won't take effect because you have SIP dialpeer
