[Asterisk-Users] Delays in sip invites.

[Ivan Cetta]

No. in any place, even i haven't any agi script in the dialplan.

exten => _87XX,1,Dial(SIP/${EXTEN},60)

This is the only i have to call the sip ata.

Also, something i forgot to mention, i have in the sip.conf and the
audiocodes the srvlookup disabled. Browsing the problem in the list i see
that someones have something similar and was dns problem. But in our case,
changing that didin't resolved it.
