I am using Cisco 7940 phones and the X-lite softphones. Both exhibit the same behavior (the delay starts out correct, and grows longer until it reaches about 3 seconds). This is a sample sip.conf entry for my 7940s and for X-Lite: [4120] ;(7940) type = friend callwaiting = yes cid_number = 4120 context = numberplan-custom-1 email = NONE fullname = CONF RM hasvoicemail = yes host = dynamic mailbox = 4120 secret = 4120 vmsecret = 1234 [4220] ;(X-Lite) type = friend callwaiting = yes cid_number = 4220 context = numberplan-custom-1 email = NONE fullname = CONF RM hasvoicemail = yes host = dynamic mailbox = 4220 secret = 4220 vmsecret = 1234 disallow = all allow = ilbc allow = gsm allow = ulaw allow = alaw I have left everything in zapata.conf default (nothing added or removed) and zaptel.conf only has: loadzone = us defaultzone = us My setup is pretty simple, all I got are Cisco 7940/X-Lite phones that work very well together, and ztdummy for MeetMe. Thanks, Nicolas. _______________________________________________ --Bandwidth and Colocation Provided by http://www.api-digital.com-- Asterisk-BSD mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-bsd
