Any Linksys / Sipura dial plan experts here

[avoipuser]

Are there any Linksys / Sipura dial plan experts here ?

The part of my existing dial plan to handle SIP broker calls is:

|*x.<:@sipbroker.com>|

so that any number starting with * is passed to SIP broker.

If I dial, for example

*258 nnnnnnnn #

where nnnnnnnn is a 8 digit VOIPtalk user number, it connects to that VOIPtalk user OK.

However if I forget to dial the # and only dial

*258 nnnnnnnn

I end up dialling a Mozambique number (the VOIP service I am logged into accepts * as the international dialling prefix and 258 is the country code for Mozambique).

I can't include the S0 terminator in the dial plan because SIP broker calls have varying lengths.

Does anyone know a way of not requiring the # terminator to be dialled ?

The Linksys software version I am using is 3.1.22(LS)

I have tried reading Answer
but this does not appear to offer a way of doing this.
