Please log in for more thread options I have a 2811 router which has one VWIC-1MFT-E1 connected to the PSTN, and one VIC2-2BRI-NT/TE connected DIRECTLY to one router and one modem (not Cisco ones). The 2811 is a H323 gateway that works properly for voice with CallManager and Cisco IP Phones (whose reach external numbers through the PRI interface). The router and the modem (whose handle data) need to access to the PSTN through the PRI interface (for remote maintenance purpose). I mean the 2811 needs to proceed the switching between its BRI interfaces and its PRI interface properly!!! We've managed to make ISDN switching to work in our lab with one 3640 router with two VIC2-2BRI-NT/TE (one connected to the PSTN and one directly connected to a router). So, I don't know why it's not working with a 2811 between a BRI and a PRI??? Our network topology network is as follow : CCM---IP---2811-PRI--PSTN | BRI | Modem&Router Does someone know how to make this configuration working ? Thanking you in advance, Regards, Benjamin PS: I have the following configuration : Current configuration : 4591 bytes ! version 12.3 service timestamps debug datetime msec service timestamps log datetime msec service password-encryption ! hostname H323GTW ! boot-start-marker boot-end-marker ! logging buffered 4096 debugging enable secret 5 ***************************** ! network-clock-participate wic 0 network-clock-participate wic 1 network-clock-select 1 E1 0/0/0 no aaa new-model ip subnet-zero ! ! ip cef ! ! no ip domain lookup no ftp-server write-enable isdn switch-type primary-net5 ! voice-card 0 no dspfarm dsp services dspfarm no local-bypass ! ! voice call carrier capacity active ! voice service pots ! voice service voip modem passthrough nse codec g711alaw ! ! voice class codec 1 codec preference 1 g711ulaw ! ! ! voice class h323 1 h225 timeout tcp establish 5 ! ! ! ! ! ! voice translation-rule 10 rule 1 /^1/ /001/ rule 2 /^2/ /002/ rule 3 /^3/ /003/ rule 4 /^4/ /004/ rule 5 /^5/ /005/ rule 6 /^6/ /006/ rule 7 /^0/ /00/ rule 8 /^8/ /008/ ! voice translation-rule 20 rule 1 /^00/ /0/ rule 2 /^01/ /1/ rule 3 /^03/ /3/ ! ! voice translation-profile modif_entrant_appelant translate calling 10 ! voice translation-profile modif_sortant_appele translate called 20 ! ! ! ! ! ! controller E1 0/0/0 framing NO-CRC4 pri-group timeslots 1-28 ! ! ! interface FastEthernet0/0 description vers CCM ip address 192.168.10.6 255.255.255.0 duplex auto speed auto h323-gateway voip interface h323-gateway voip bind srcaddr 192.168.10.6 ! interface FastEthernet0/1 no ip address shutdown duplex auto speed auto ! interface Serial0/0/0:15 no ip address no logging event link-status isdn switch-type primary-net5 isdn incoming-voice voice isdn negotiate-bchan resend-setup isdn sending-complete no cdp enable ! interface BRI0/1/0 no ip address isdn switch-type basic-net3 isdn overlap-receiving isdn protocol-emulate network isdn layer1-emulate network isdn incoming-voice voice isdn sending-complete isdn skipsend-idverify line-power ! interface BRI0/1/1 no ip address isdn switch-type basic-net3 isdn overlap-receiving isdn protocol-emulate network isdn layer1-emulate network isdn incoming-voice voice isdn skipsend-idverify line-power ! ip classless ip route 0.0.0.0 0.0.0.0 192.168.10.254 ! ! ip http server ip http authentication local ip http secure-server ! ! ! ! control-plane ! ! ! voice-port 0/0/0:15 translation-profile incoming modif_entrant_appelant cptone FR ! voice-port 0/1/0 compand-type a-law cptone FR ! voice-port 0/1/1 compand-type a-law cptone FR ! ! ! dial-peer cor custom ! ! ! dial-peer voice 10 pots translation-profile outgoing modif_sortant_appele destination-pattern .T progress_ind setup enable 3 progress_ind alert enable 8 progress_ind progress enable 8 progress_ind connect enable 8 incoming called-number . no digit-strip direct-inward-dial port 0/0/0:15 forward-digits all ! dial-peer voice 11 pots destination-pattern 7158 progress_ind setup enable 3 progress_ind alert enable 8 progress_ind progress enable 8 progress_ind connect enable 8 incoming called-number 7158 direct-inward-dial port 0/1/0 forward-digits all ! dial-peer voice 12 pots destination-pattern 7157 progress_ind setup enable 3 progress_ind alert enable 8 progress_ind progress enable 8 progress_ind connect enable 8 incoming called-number 7157 no digit-strip direct-inward-dial port 0/1/1 forward-digits all prefix 7157 ! dial-peer voice 100 voip description Vers Publisher preference 1 destination-pattern 71.. voice-class codec 1 voice-class h323 1 session target ipv4:192.168.10.2 incoming called-number 71.. dtmf-relay h245-signal h245-alphanumeric no vad ! dial-peer voice 110 voip description Vers Subscriber preference 2 destination-pattern 71.. voice-class codec 1 voice-class h323 1 session target ipv4:192.168.10.3 incoming called-number 71.. dtmf-relay h245-signal h245-alphanumeric no vad ! dial-peer voice 200 voip description Vers Publisher preference 1 destination-pattern 30.. voice-class codec 1 voice-class h323 1 session target ipv4:192.168.10.2 dtmf-relay h245-signal h245-alphanumeric no vad ! dial-peer voice 210 voip description Vers Subscriber preference 2 destination-pattern 30.. voice-class codec 1 voice-class h323 1 session target ipv4:192.168.10.3 dtmf-relay h245-signal h245-alphanumeric no vad ! gateway timer receive-rtp 1200 ! ! ! line con 0 password 7 ***************************** login line aux 0 password 7 ***************************** login line vty 0 4 password 7 ***************************** login ! scheduler allocate 20000 1000 ! end | |||||||||||||

Please log in for more thread options Hi,
Have a look at http://www.cisco.com/en/US/tech/tk652/tk653/technologies_tech_note09186a00804794c6.shtml. From your debug output I cannot see the router continue call setup to the PSTN. Have another look at your dial-plan. Erik | |||||||||||||

0x0165 It seems the configuration is almost OK but the communication between my access router (connected to the BRI interface of the 2811 router) and my remote router can't be established. Is it a problem of PRI configuration? Is it a question of configuring a dedicated chanel on the PRI ? Could you please give me your feedback about that ? Thanking you in advance Regards Benjamin | |||||||||||||

Please log in for more thread options It looks like a seperate call is being placed in each direction. The
connection should come up with a single call. I've seen this before on more than one occasion - bug perhaps - it had to do with the CHAP configuration and IOS version. Specifically, if one-way authentication was configured, the routers placed two calls, and the challenge happened on one channel, but never got the response on that same channel. If two way authentication was configured, a single call was placed, and the challenge/response took place on the same channel. I'd suggest posting the configs for both routers, maybe even the output of "debug ppp authentication" as well....... Perhaps the easiest way to rule this out would be to eliminate ppp/authentication from the conigurations and try again...... -ja > Hello,
