Enabling DTMF relay from Dispatch to Analog Phone

[keith]

When working with dial-up phones,

Remember to configure on voip dial-peer with a fictitious number, say 9999, or 1100, or else this way (‘.’ below is a single dot):



dial-peer voice 1100 voip

incoming called-number . <<--- *
dtmf-relay h245-alphanumeric <<--- **

Hi Yuri,



Thanks for the debugs!

I'm sorry I can not accept your call yesterday I was offshift on that time.



I have run through the debugs and found something interesting:



Aug 23 16:49:57.571: //3602/BC3901893CB7/H323/cch323_determine_source_ip_group_info: No Source IP group match with Incoming Called Number

Aug 23 16:49:57.575: //-1/BC3901893CB7/CCAPI/cc_api_call_setup_ind_common:
Interface=0x47DCA034, Call Info(
Calling Number=,(Calling Name=)(TON=National, NPI=ISDN, Screening=Not Screened,
Presentation=Allowed),
Called Number=1001(TON=National, NPI=ISDN),
Calling Translated=FALSE, Subscriber Type Str=Unknown, FinalDestinationFlag=TRUE,
Incoming Dial-peer=0, Progress Indication=NULL(0), Calling IE Present=TRUE,



It seems there was no matched configured incoming dial-peer so the default one was matched which is the dial-peer 0.



I'm just wondering if we could configure a dummy incoming dial-peer:



dial-peer voice x voip

incoming called-number . <<--- *
dtmf-relay h245-alphanumeric <<--- **
codec g711ulaw <<--- ***
no vad <<--- ****

* will match with all incoming called number

** so ' dtmf-relay h245-alphanumeric' will be applied for all calls

*** all calls will use this codec

**** no vad will be also activated



I hope this will help us out!

Please let me know if you have further questions or concerns. I' will be here today for more 9 hours from 08:00 to 17:00 CEST (GMT+2)



Best regards,

Tibor
