[asterisk-users] What don't I get about SIP?

[Mike]

Thanks Dave.  Unfortunately I've been through this already.  I understand
that digitmap are used to automatically press "send" when a certain pattern
is reached.  Nowhere can I say "if the pattern isn't fully match within x
seconds then consider it a bad extension".

That`s the only relevant thing I haven`t yet found how to do.

Regards,

Mike

You want to look at the dialplan section in your sip config file or on the
device's web config. Specifically the dialplan.digitmap and
dialplan.impossibleMatchHandling settings. (These are explained in detail in
the Admin Guide available on polycom's website). If you don't want the phone
to do any dial plan matching you should make the digitmap accept any dial
string (ie ".") and set your timeouts appropriately.
