Hello Experts, I was on the vRack today and experienced a strange behavior between H323 and CUCM.
BR1 router was running H323, connected to CUCM. All calls, both inbound and outbound between BR1 and PSTN, failed, they rang once and then get dropped. Failed message under "Debug ISDN Q931" was: Bearer capability not implemented When I put the phones into SRST mode, all inbound and outbound calls worked fine. I could see ISDN status is up with multiple frames established. The router was behaving normally in most ways. Below is my BR1 configuration, can you help to take a look and let me know what I had missed? Thank you in advance. sh run Building configuration... hostname BR1-RTR ! clock timezone EST -5 clock summer-time EDT recurring network-clock-participate wic 0 network-clock-select 1 T1 0/0/0 ! ! no ip domain lookup ip domain name proctorlabs.com no ipv6 cef ! multilink bundle-name authenticated ! ! isdn switch-type primary-ni ! ! ! voice service voip allow-connections h323 to h323 allow-connections h323 to sip allow-connections sip to h323 allow-connections sip to sip ! ! ! ! ! ! ! ! ! ! ! ! ! ! ! voice translation-rule 1 rule 1 /.*\(....$\)/ /\1/ ! voice translation-rule 999 rule 15 // /\0/ type any subscriber plan any isdn ! voice translation-rule 1000 rule 10 // /\0/ type national national plan isdn isdn rule 15 // /\0/ type any subscriber plan any isdn ! voice translation-rule 1001 rule 15 // /+\0/ type any international plan any isdn ! voice translation-rule 9999 rule 15 // /\0/ type any unknown plan any isdn ! voice translation-rule 91000 rule 15 // /\0/ type any subscriber plan any isdn ! voice translation-rule 91001 rule 15 // /\0/ type any national plan any isdn ! voice translation-rule 91002 rule 15 // /\0/ type any international plan any isdn ! ! voice translation-profile 1 translate called 1 ! voice translation-profile 1000 translate calling 1000 translate called 91000 ! voice translation-profile 1001 translate calling 1001 translate called 91001 ! voice translation-profile 1002 translate calling 1002 translate called 91002 ! voice translation-profile 999 translate calling 999 translate called 9999 ! ! voice-card 0 no dspfarm ! ! ! ! ! archive log config hidekeys ! ! ! ! ! controller T1 0/0/0 framing esf linecode b8zs pri-group timeslots 1-3,24 ! controller T1 0/0/1 framing esf linecode b8zs channel-group 0 timeslots 1-24 ! ! interface Serial0/0/0:23 no ip address encapsulation hdlc isdn switch-type primary-ni isdn incoming-voice voice isdn bchan-number-order ascending isdn outgoing display-ie isdn outgoing ie redirecting-number no cdp enable ! interface Vlan240 ip address 10.10.201.1 255.255.255.0 ip helper-address 10.10.210.10 h323-gateway voip interface h323-gateway voip bind srcaddr 10.10.201.1 ! ! ! ! ! control-plane ! ! ! voice-port 0/0/0:23 translation-profile incoming 1 ! ! ! ! ! dial-peer voice 1 pots incoming called-number .T direct-inward-dial port 0/0/0:23 ! dial-peer voice 2 voip destination-pattern 1... session target ipv4:10.10.210.11 dtmf-relay h245-alphanumeric codec g711ulaw no vad ! dial-peer voice 3 voip preference 1 destination-pattern 1... session target ipv4:10.10.210.10 dtmf-relay h245-alphanumeric codec g711ulaw no vad ! dial-peer voice 999 pots translation-profile outgoing 999 destination-pattern 9%911$ no digit-strip direct-inward-dial port 0/0/0:23 forward-digits 3 ! dial-peer voice 1000 pots translation-profile outgoing 1000 destination-pattern 9[2-9]......$ no digit-strip direct-inward-dial port 0/0/0:23 forward-digits 7 ! dial-peer voice 1001 pots translation-profile outgoing 1001 destination-pattern 91[2-9].........$ no digit-strip direct-inward-dial port 0/0/0:23 forward-digits 11 ! dial-peer voice 1002 pots translation-profile outgoing 1002 destination-pattern 9011T direct-inward-dial port 0/0/0:23 prefix 011 ! ! ! ! gatekeeper shutdown ! ! telephony-service srst mode auto-provision all max-ephones 2 max-dn 20 preference 3 no-reg ip source-address 10.10.110.2 port 2000 max-conferences 8 gain -6 transfer-system full-consult transfer-pattern .T secondary-dialtone 9 create cnf-files version-stamp 7960 Dec 07 2010 10:14:21 ! ! ephone-dn 1 octo-line number 1002 label 1002 description +16178631002 name +16178631002 preference 3 ! ! ephone 1 device-security-mode none mac-address 001D.E041.DE1B type 7961 button 1:1 !
