No dial plan


UCM6202. Added an outbound route: _. in order to dial **21XXXXXXXXXX#. With a Yealink T23G no problems. With any Grandstream phones I get a no dial plan message.

Thanks in advance for any help.


add **x+ to the GS dial plan


Is that to a PSTN trunk?


Sorry, it messed up the formatting. The rule is: _**21X.

It is PSTN. Gonna try what you suggested later.
