Overlap Dialing

Hi NetPro,

I have a 3845 running as PSTN gateway with 3 ISDN PRI ports. SIP trunks connect this gateway to a few CME's.

Outgoing calls are established not quick enough(for some users) as it takes aboiut 8 seconds to call a mobile phone. I find a command 'isdn overlap-reeiving' in the doc, but is it used for incoming calls? How can I configure overlap dialing for outgoing calls to fasten the connections?

Thanks in advance.

Re: Overlap Dialing

You can turn off some of the parameters in CME. Through that you can fasten the connections. Configuring Overlap Sending and Receiving with Cisco CallManager

Hi Ursula,

Thank you very much for the reponse.

I do not have a CallManager. I am looking for the configurations in cme or the PSTN gateway router.
