Hi Someone has any idea how modem 56k to GSM modem works?.   We have install a 2901 router between Digital PBX and ISDN ISP using E1 line.   Voice calls and modem 56k to moden 56k are working well.   But calls from modem 56k to GSM modem not work. Costumer dial a prefix GSM for data + GSM number. We send all these number to ISP. I don't know if I have to process this call with a particular configuration on D channel or not. The PBX was connected to the ISP directly before and that worked.   I have looking for information but I don't find anything releated from Cisco, only for UTMS modems. I think this is not UTMS modem.   Thank you   Best Regards ... View more

Hi   We have used a 2901 to bypass the calls between digital PBX and ISDN connection.   So the topology is PBX--E1--VGW-- E1--ISDN ISP.   Voice calls are working well but modem not, there is a modem on the PBX side needs to communicate with another on the PSTN   Using debug isdn q931 and debug voip ccaip inout I only see the destination modem disconnect the communication after few seconds as a normal clereance (diconnect cause 16)?   This is the configuration of the E1 Serial port.   Port to ISP ! interface Serial0/0/0:15  no ip address  encapsulation hdlc  isdn switch-type primary-net5  isdn incoming-voice voice  trunk-group ISP  no cdp enable ! Port to PBX ! interface Serial0/0/1:15 no ip address encapsulation hdlc isdn switch-type primary-net5 isdn all-incoming-calls-v120 isdn overlap-receiving T302 10000 isdn protocol-emulate network isdn incoming-voice voice trunk-group PBX no cdp enable ! Dial Peer incoming from PBX ! dial-peer voice 1000 pots  description incoming Calls  incoming called-number .T ! Dial Peer ISP ! dial-peer voice 1003 pots  trunkgroup ISP  description outgoing ISP  destination-pattern [29]........ !   Any advise to troubleshoot this?   Thank you   Best Regards ... View more

Hi I need some help please.  We contract a new SIP Service provider and I have this problem.  This is the problem: When I call from mobile to UCCX IVR.  It tranfer the call to agent and we don't hear the ringback tone on Mobile.  This is the flow: MOBILE ---> SBC SERVICE PROVIDER --SIP->OUR SBC ---> UCCX -Transfer to- CUCM.  We use UCCX only for IVR.  Some test.  If we call from mobile to CUCM internal IP Phone the RINGBACK is OK.  If we call from mobile to CUCM interna IP phone and it transfert directly to other IP phone the RINGBACK is OK If we call internally from CUCM IP phone to IVR Route Point we can hear the RINKBACK When UCCX transfers the call to agent. Note that I  hear RINGBACK not MOH. The  Network Hold Audio Source are None for CTI ports in control group.  I would like to know if the ringback signal is sending by UCCX, I haven't had the oportunity to check the traces yet I think it could be a 180 RINGING issue may be SP expect 183 with SDP because they have not media to send the RINGBACK. But the fact that if we call directly to CUCM and works and if we call to UCCX IVR fails.. confusing to me because in both case the 180 RINGING is sending by CUCM, Right? Thank you  Best Regards ...

Hi I have a new deployment in a costumer that wants to connect to VoIP Internet Service provider for outgoing calls. This is trunk is connecting directly in CUCM (no CUBE involve) The problem is on the firewall that it doesn't change the URI domain from Public IP to CUCM Internal IP when apply NAT for incoming calls. The Ing in charge have no much Idea to enable this, so CUCM refuse the call. Meanwhile firewall guy try to figure out to fix this. I'm thinking to try modify the URI to use a script normalization in trunk but I am not sure if I am able to do this.  can Sip normalization script be applied on Incoming Notify from in CUCM Trunk? I know in cube you can not, but for CUCM I don't know. Thank you Best Regards. ... View more

Hi We have configured 802.1x ports to authenticates computers, phones, APs, and printers again ISE. ISE detects the device type and it provide a VLAN for it depending of the profile. But we have a problems with phones. Some times in random phones without no reason phone reset and after authorization the port is administrative shutdown and no shutdown itself, and sometimes the phone recovers, sometimes keep reseating indefinitely. There is not any patron, we have had this problem with 2 different type phones 7841 and 8851, on  different stacks. The strange thing is when this happen.. you connect the phone to another switch stack and it works, or not, it is very random. But if we remove the port authorization commands on the port it is failing and configure it on vlan voice, it works. On ISE there is not any error on the log, on the switch, this is we can see.
