Solved: DTMF tone from SIP client phones does not work on CME 8.6

gossa1973 · ‎07-26-2012

We have SIP trunk with CME 8.6 and 10 SCCP (7960,7975) phones, also UM with Exchange 2010 , everything work perfectly until we added two SIP client phones.

SIP client phones 9971 and 7906 have issue with sending DTMF signals.

From both SIP phones I can call and receive calls but when I call some number with auto attended or voice mail on internal or external number I have problem to choose options by sending DTMF tones,

I hear DTMF tones but destination party does not.

I can leave message, which means that I have two way communication.

I notice this trying to access ours voice mailbox on Exchange 2010 I can make call but no DTMF command are recognized I cannot enter PIN for mailbox I hear DTMF tones but UM does not

everything is normal with SCCP clients phones or external call forwarded to voicemail DTMF tones are passed, problem localized on SIP clients phones.

My configurations for SIP and those two phones are

voice service voip

gcid

no cti shutdown

callmonitor

allow-connections h323 to sip

Any idea what is wrong or do you how can I troubleshot the problem

Just to add to the post above, could you try changing the dtmf relay under the voice register pool to rtp-nte and do a create profile under voice register global.

Can you do a test call and send a debug ccsip messages and debug voip rtp session named-event.

Ok so from the trace, the DTMF type on both cme and exchange are the same.

Can you send me debug voip rtp session named-event. Did you change the dtmf relay type on the phone as suggested above to dtmf-relay rtp-nte?

Just to add to the post above, could you try changing the dtmf relay under the voice register pool to rtp-nte and do a create profile under voice register global.
