Thanks to John Lodden's help, he was able to determine that the cause of my inability to dial 800 numbers through FWD or SIPphone was due to the Grandstream phone and the order of codecs in sip.conf
This order breaks the 800 dialing: disallow=all allow=ulaw allow=alaw allow=g729 However, this order allows it: disallow=all allow=g729 allow=ulaw allow=alaw Barton _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users
