I recently just completed installing several Cisco VG204 & VG202 gateways at my office. We use a mix of real fax machines and a Linux server running Hylafax. The Hylafax server is used only for receiving faxes. No users use the Hylafax server to send faxes because we have real physical fax machines located strategically throughout the office.
When receiving faxes to the physical fax machines, the faxes are received just fine. However, when faxes are received to numbers associated with the Hylafax server, we run into an issue. Some, if not all received fax pages end up being "cut off". That is, there is random garbage near the end of a fax page which is unreadable. However, everything above that garbage is readable & faxed fine. Prior to migrating to the VG gateways, all received Hylafax faxes were normal. I'm thinking it has to do with the way my faxes are set up on the Voice Gateway. Below is my relevant config on the VG202 (the config is identical across all the VGs). Any ideas? I'm using SCCP for all my phones because I was told it was the easiest & recommended way to set up the VoIP network. version 12.4 ! stcapp ccm-group 100 stcapp ! stcapp feature access-code ! voice service voip modem passthrough nse codec g711ulaw ! voice-card 0 ! interface FastEthernet0/0 ip address 172.21.xxx.xxx 255.255.255.0 duplex auto speed auto ! interface FastEthernet0/1 no ip address shutdown duplex auto speed auto ! ip forward-protocol nd ip route 0.0.0.0 0.0.0.0 172.21.xxx.xxx ! voice-port 0/0 timeouts initial 60 timeouts interdigit 60 timeouts call-disconnect 3 timeouts ringing infinity ! voice-port 0/1 timeouts initial 60 timeouts interdigit 60 timeouts call-disconnect 3 timeouts ringing infinity ! ccm-manager fax protocol cisco ccm-manager sccp local FastEthernet0/0 ! mgcp fax t38 ecm mgcp behavior g729-variants static-pt ! sccp local FastEthernet0/0 sccp ccm 172.21.xxx.xxx identifier 1 priority 1 version 7.0 sccp ! sccp ccm group 100 associate ccm 1 priority 1 ! dial-peer voice 1000 pots service stcapp port 0/0 ! dial-peer voice 1001 pots service stcapp port 0/1 ________________________________ Hyoun Kim * Network Administrator I - East Division 640 Broadmor Blvd * Suite 80 * Murfreesboro, TN 37129 ' 615.217.6245 * ' 859.312.6941 * 7 615.217.6255 * * [email protected] E-MAIL CONFIDENTIALITY NOTICE: The contents of this e-mail message and any attachments are intended solely for the addressee(s) and may contain confidential and/or legally privileged information.
