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.

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
