-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I've been struggling with an ongoing problem the last month.
Here is the layout of the wiring: T1 from ISP > DiTech Echo Cancel device > Voice Channel-Bank (same) T1 from ISP > (same) DiTech Echo Cancel device > asterisk1 server zap card > fax channel bank (same) T1 from ISP > (same) DiTech Echo Cancel device > asterisk1 server zap card > asterisk2 server Now, let me explain the symptoms. d-channel errors on the asterisk1 server on span1 (which is the line coming from the echo cancel from the ISP). asterisk2 server isn't being used as far as I can tell. I've got a red alarm on the port on asterisk1 that asterisk2 is plugged into. faxes through the fax channel bank are working most of the time. There seems to be problems with multipage faxes. Not isolated to a particular port on the channel bank. As I understand it, echo cancel for faxes is a bad thing, so I don't understand why the previous IT Admin here setup the system as such. Some voice phones on the voice channel banks were not recognizing tones when dialing. That seems to have been resolved after power cycling the channel bank a few times, and restarting asterisk2 (odd that there doesn't seem to be anything active on asterisk2) I've been working with the ISP on the d-channel stuff, and things seem to get a little better as they reset equipment, but the d-channel errors have not gone away. I really need advice on these problems. From what I've said, where do you think the problem lies? in the channel banks? in the echo canceller? in the asterisk2 or asterisk1 server? With the ISP? - -- Regards, Justin Phelps IT Director Eye Center of North Florida 850.522.7952 - Office 850.522.9829 - Fax 850.832.0249 - Cell www.eyecarenow.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org iEYEARECAAYFAklKiIwACgkQfV4idVrZqT+NWgCgm/jh4wtludHP5vu7Eh8RASch P4YAoIwy1INpEvDGQ0f95z0EITASqdod =RtFM -----END PGP SIGNATURE----- _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
