Hi, you are not calling any number because the 9 is absorbed being it pots DP. Add "no strip-digit" and PBX should connect you to PSTN. You can also do a DP like 9.....T this way you can call directly, no need to wait for dialtone.

Please rate post if it helps!

Dear freind

Are you using CM or CME ? Sometime you can configure "secondary dialtone" to emulate PSTN dialtone.

there is just ericcson MD110 and cisco gateway (CISCO 2811)

we are trying to make call from PBX extentions.

The 2821 is connected to both PBX and PSTN ? And to for which purpose ?

Please specify with a diagram all that is connected as requested before.
