I'm trying to setup T37 on a 2431 IAD FXS port for onramp services but the only way I got it to work I had to hard code the number in the mail to field. Any ideas?

I have 2431 IADs with FXS ports using SIP and when we make outbound calls to the PSTN ring back is good but as soon as the calls connects we can hear a loud pop or click that I don't hear if I use another type of IAD.

We are getting ppp authentication failure in a ppp over frame relay setup with a carrier using 2 PVCs. One for voice and one for data. Can you provide a sample configuration?

A Fax server from Castelle connected to a VG248 is missing pages randomly. Sometimes it works and sometimes it doesn't. Specially if we receive long faxes like 14 pages we could miss one or two pages. I have disable all fax relay setting on the vg248...
