I have a set up of an IAD with FSX for FAX and a T1/PRI to the PSTN, both gateways are running mgcp. Am I the only one who finds that fax passthrough with MGCP is less than sterling? Is there anyone out there who has a different method except to tell the customer to forget it and run the fax machines directly? I have a lot of instances of missing pages. I have both gateways at the lastest code levels and have had endless conversations with the TAC over it. Also, I'm running CM3.2
I feel your pain....and by what you describe, your problem is with Fax Relay enabled and not Fax passthrough. DISABLE FAX RELAY AT EVERY PLACE YOU CAN (if single site)! Check your MGCP gateways, uncheck Fax Relay. If you have VG248's....disable there. It's everywhere and sounds exactly what happens when Fax relay is enabled. Once fax relay is disabled, your faxes will run perfectly. believe me...I lived this torment....
I've been running H323 Vg200s for fax machines for about a year no problems, I've recently had a need to run one on MGCP (so I can share a line between an analog port and an IP phone for an external ringer) and had no luck whatsoever - latest IOS revisions don't seem to have much control over use of passthrough/relay.
The only MGCP device I've had work for fax is the 6624 blade for the 6500 - this has an option in CM to disable fax relay, and works fine!
Are you willing to share some config with me. I don't have as much experience with the H323 and I know if you don't match up the peers correctly, you can be attached to the default which is no good. Also, are you running your PSTN connection via MGCP or H323??
I'm not able to access my old voice mail messages all of a sudden. The recording says something like 'the message is currently not available'. This has never happened before in all the years I have been using this system. I have t...
If you have 2 ISR routers, one acting as Failover, do we need to have both the same number of SRST licenses on the 2 routers?
No. You will only need the SRST licenses on the primary router. Because this feature...
