Is it possible for a Cisco 2620XM to be misconfigured and cause faxes to run half duplex?
Symptom: fax pages dying at half the page, or simply coming through missing half the data. Fax seems to connect and go through successful...just missing data.
Topology: analog fax-->audiocodesFXS-->ethernet-->2620XM--PRI to PSTN
SIP based IP telephony with Audiocodes analog gateways. Anyone have any experience troubleshooting faxes across VoIP? Is there a command that needs to be issued at the dial-peer level to force full duplex? Seems like it would just know to do that...why would half duplex even be an option?
1) What type of Fax over ip protocol does Audiocodes support ?
2) Can you make a call from FXS port on Audiocodes analog gateway out to PRI and what type of voice quality do you have ?
3) What type of codec are you using between Audiocodes and Cisco ?
4) To cover all ground check your ethernet interface on 2620 and make sure you do not have any errors or collisions.
Normally in fax world you do not have 2 fax machines talking at the same time a single fax machine is who originates call sends data to terminating fax machines. The terminating fax machines usually negotiates capabilites with originating fax machines which we call it training. Once this is done the terminating fax machines collects data that is send from originating fax machines.
The short answer is that you don't.... That isn't entirely true while at
the same time it kind of is, but for the most part you don't configure
the softkeys. You enable or disable them via TCL. Here is the long
answer. Be sure to read the whole thing or e...
