DTMF problem on CME router

[kiranoddiraju]

Guys,

I have a 2811 CME gateway connect to the Telco via SIP. I have no problem with inbound and outbound calls, they work fine but I have problem with DTMF. The Telco says they are not receiving any digits from our side. I have the below dial-peer config on my side, please let me know what I need to change...

dial-peer voice 9 voip

description <<< Outbound to Telco >>>

translation-profile outgoing outgoing_digits

destination-pattern 9.T

voice-class codec 1

session protocol sipv2

session target ipv4:xxx.xxx.xxx.xxx

dtmf-relay sip-notify

no vad

!

The debug is

debug voip rtp session named-event

You may also want to remove sip-notify from your dial-peers..Most likely your provider doesnt support this...

Hi!

Here's the SDP from the INVITE sent to ITSP:

Then, we can see the NSE Events for DTMF "108", did you dial 108 for DTMF testing?

Not sure why ITSP is not getting those NSE events.

Please let us know if anything.

Dear Jorge,

Thanks for your obvervation. If my ITSP can't get NSE event then what causes the problem? Is it regarding DSP or

DTMF relay issue?.. Please suggest me...

Thanks in Advance.

[Matheus Lopes]

I've had the same issue for the DTMF and I was getting the errors below.

I've fixed my issue changing the parameter on SIP profile to Early Offer support for voice and video calls Mandatory (insert MTP if needed) and DTMF method to (RFC 2833) on the SIP Trunk to the CUBE.

As the OP was asking about CME your answer is unrelated and apart from this the post is set as answered, so it would be somewhat unnecessary to reply to it.
