voip

[prabath]

I have a problem with my voip setup so I created a lab setup to test this.

Tele phone 1-----PBX----3662----ethernet----1750/1751-----tele phone 2

telephone 2(1750)-----telephone 1 (3 seconds between dialing digits & hearing ring back tone from telephone 2)

telephone 2(1751)-----telephone 1 8 seconds

Can anyone help me to reduce this time period in 1751?

What are the interfaces between the PBX and the 3660 and can we see the configs?

It is E1 (NM-HDV-2E1)

I would like to see how this is resolved too ....

 

[prabath]

Resolved by removing
call rsvp-sync
in 3662 router....
Can't believe.... Can anyone explane this ?
(I think this command is used to combine voice with rsvp on the interface....But there were no rsvp on ethernet that we used for testing....

Another problem is why this delay occured only when call setup towards 1751 but not for 1750....
I am not mastering VOIP so I can't make any arguments..
