We have some Polycom IP 330 SIP handsets connected to a Trixbox.  Unfortunately, when using the default SIP.cfg that is downloaded via TFTP to the handsets, if the phone was off the hook (ie. a dial tone was already audible) the handsets would appear to time-out and give the message “All Circuits are Busy Now”. On looking at the call in the CLI (asterisk -rvvvv) it was apparent that only the first 9 digits were being dialled.

The solution was to edit the the /tftpboot/sip.cfg and look for the line that says:

<digitmap dialplan.digitmap=”[2-9]11|0T|011xxx.T|[0-1][2-9]xxxxxxxxx|[2-9]xxxxxxxxx|[2-9]xxxT” dialplan.digitmap.timeOut=”3|3|3|3|3|3″/>

and replace with the correct number of digits for calls in your country…

<digitmap dialplan.digitmap=”[2-9]11|0T|011xxx.T|[0-1][2-9]xxxxxxxxxxx|[2-9]xxxxxxxxxxx|[2-9]xxxT” dialplan.digitmap.timeOut=”3|3|3|3|3|3″/>

You then need to restart the handsets in order for this to work.
