Dial out delay. Sip -->FXO

Hardware:
Cisco 7960 (sip firmware)
SpoTel® TDM1600Pv2 (Version 2) 8 port FXO/FXS card
the PC is a dual core with an SSD (pretty sure it’s performance is not an issue)

I can dial from extension to extension instantly (IE 201, dial, ring)

However, when I dial to outside lines:

NNNNNNNNNN dial, proceeding (100) for about 2 seconds, then the counter on the phone gets to 6 seconds before it starts ringing.

Is this normal? is there anything I can do to improve the dialing out performance? I’ve got over my outbound routes, they all look pretty good.

I know on oldschool modems, there were variables you could set to improve the atdt dialing speed, does the same apply here? was it not something like ats11=50 ?

I just forced my staff to switch from an oldschool medridian PBX system, and so far all I’ve gotten is complaining.

They don’t like the line/hold/transfer system, but I’m sure they will get over it, but they also don’t like the delay in dialling out.

Hello:
Usually the phone will ring in 4-5 seconds. It is better to check the FXO setting and dahdi_test for the status.

Your problem is your “dialstrings” not being “closed”, if you dial something which is indeterminate then you will have to wait the default “timeout” (default is 5 seconds) until the call completes.
