Hello All, I am facing an issue with dtmf-relay. PhoneA registered to CUCM (SiteA) calls PhoneD registered to CUCME (Site C). Between Regions G729 codec is negotiated. PhoneD call-forward no answer to Voicemail. CUE integrated with CME. After leaving the Voicemail from PhoneA to PhoneD, when I press # key to send the Voicemail, it is not recognized.
Here is my scenario and the configuration. (PhoneA) -- CUCM ----SIP TRUNK ----CUCME (PhoneD) ---> CUE. voice service voip ip address trusted list ipv4 0.0.0.0 0.0.0.0 allow-connections h323 to h323 allow-connections h323 to sip allow-connections sip to h323 allow-connections sip to sip fax protocol t38 version 0 ls-redundancy 0 hs-redundancy 0 fallback none h323 sip bind control source-interface Loopback0 bind media source-interface Loopback0 registrar server expires max 600 min 60 ! voice class codec 1 codec preference 1 g711ulaw codec preference 2 g729r8 ! telephony-service sdspfarm units 3 sdspfarm transcode sessions 4 max-ephones 5 max-dn 10 ip source-address 3.3.3.3 port 2000 load 7945 term45.default.loads time-zone 28 time-format 24 date-format dd-mm-yy voicemail 3600 max-conferences 8 gain -6 call-forward pattern .T moh "music-on-hold.au" dn-webedit transfer-system full-consult transfer-pattern .T create cnf-files ! sccp local Loopback0 sccp ccm 10.0.10.160 identifier 2 version 7.0 sccp ccm 3.3.3.3 identifier 1 version 7.0 sccp ip precedence 3 sccp sccp ccm group 1 associate ccm 1 priority 1 associate ccm 2 priority 2 associate profile 1 register BR2-IOS-XCODE associate profile 2 register BR2-IOS-CFB keepalive retries 5 switchover method immediate switchback method immediate switchback interval 15 ! dspfarm profile 1 transcode codec g729r8 codec g711ulaw codec g711alaw codec g729ar8 codec g729abr8 maximum sessions 4 associate application SCCP ! dspfarm profile 2 conference codec g711ulaw codec g711alaw codec g729ar8 codec g729abr8 codec g729r8 codec g729br8 maximum sessions 2 associate application SCCP ! dial-peer voice 1000 voip destination-pattern [15]...$ session protocol sipv2 session target ipv4:10.0.10.160 incoming called-number . voice-class codec 1 dtmf-relay sip-notify no vad ! dial-peer voice 3600 voip destination-pattern 3[16]00$ session protocol sipv2 session target ipv4:10.10.202.100 incoming called-number 399[89].... dtmf-relay sip-notify codec g711ulaw no vad ! *On the CUCM, I did the following,*Media Termination Point Required (Checked) MTP Preferred Originating CodecRequired Field: g711ulaw DTMF Signaling MethodRequired Field: No preference Non Secure SIP Trunk Profile: I am using TCP+UDP for INCOMING + Accept Unsolicited Notification (Checked).
