Hello all,   I need some major support. I have a ticket open already but CISCO tech support has not made any contact. I took over this network to get it running for the military standards to allow secure calls. It was in really bad shape before I got here. I reconfigured the system to run MGCP as this is required to be able to function for secure calls via either STE's aor Vipers by GD. The problem I have is now is FAX's, Modems do not work not even sure my firealarms are really reporting correctly and rekeying of secure terminal is really flaky and secure calls do not last very long. I have read tons of documentation such as the v.150 MER essential requirement as well as my military deployment guide. My equipment meets all the specs. Below is the configuration currently and im game for changes im aslo assuming I have CUCM setup correctly as well.. I need help and advice please.   Telco-PRI-GW(ISR-4351)-MGCP-CUCM-SCCP-VG350-FAX/MODEM/FireAlarms/Secure STE phones Telco-PRI-GW(ISR-4351)-MGCP-CUCM-SIP-VIPER =====ISR-4351======== voice service voip no ip address trusted authenticate media bulk-stats allow-connections h323 to h323 allow-connections h323 to sip allow-connections sip to h323 allow-connections sip to sip fax protocol t38 version 3 ls-redundancy 0 hs-redundancy 0 fallback pass-through g711ulaw modem passthrough nse codec g711ulaw modem relay sse redundancy interval 16 sip call service stop ! mgcp mgcp call-agent ***.***.***.*** 2427 service-type mgcp version 0.1 mgcp dtmf-relay voip codec all mode nte-gw mgcp rtp unreachable timeout 1000 action notify mgcp modem relay voip mode sse redundancy packet 5 mgcp modem relay voip sprt retries 10 mgcp modem relay voip sprt v14 receive playback hold-time 20 mgcp modem relay voip sprt v14 transmit hold-time 12 mgcp modem relay voip sprt v14 transmit maximum hold-count 22 mgcp codec clear-channel packetization-period 20 mgcp ip qos dscp cs6 signaling mgcp playout adaptive 15 15 30 mgcp package-capability mf-package mgcp package-capability rtp-package mgcp package-capability sst-package mgcp package-capability pre-package mgcp package-capability mdste-package mgcp package-capability fm-package no mgcp package-capability fxr-package no mgcp timer receive-rtcp mgcp sdp simple mgcp validate call-agent source-ipaddr mgcp fax t38 inhibit no mgcp fax-relay sg3-to-g3 mgcp rtp payload-type g726r16 static mgcp bind control source-interface GigabitEthernet0/0/0.252 mgcp bind media source-interface GigabitEthernet0/0/0.252 mgcp behavior rsip-range tgcp-only mgcp behavior comedia-role none mgcp behavior comedia-check-media-src disable mgcp behavior comedia-sdp-force disable mgcp rtp payload-type nte 101 ! mgcp profile default ! sccp local GigabitEthernet0/0/0.252 sccp ccm ***.***.***.*** identifier 1 version 7.0 sccp ccm ***.***.***.*** identifier 2 version 7.0 sccp ccm ***.***.***.*** identifier 3 version 7.0 sccp ! ccm-manager fallback-mgcp ccm-manager redundant-host ***.***.***.*** ***.***.***.*** ccm-manager mgcp no ccm-manager fax protocol cisco ccm-manager config server ***.***.***.*** ***.***.***.*** ccm-manager config ======VG-350========= voice service voip 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 modem relay latency 250 modem relay sse redundancy packet 2 modem relay sse t1 2100 modem relay sse retries 5 modem relay sprt retries 10 modem relay sprt v14 receive playback hold-time 32 modem relay sprt v14 transmit hold-time 12 modem relay sprt v14 transmit maximum hold-count 22 sip call service stop ! voice-port #/0/# timeouts initial 60 timeouts interdigit 60 timeouts ringing infinity ! ! dial-peer voice ####### pots service stcapp port #/0/##             ...
