Hi All,
I'm currently using the setup below:
Nortel PBX ------E1/R2------- Cisco 3660 (NM-HDV-1E1-30E)
The Nortel PBX has the following description:
Make: Nortel Meridian SL1 - XT
Version: 1211 Release 16 Issue 91
The Cisco 3660 has the following IOS:
Version 12.1(5)T4
I'm currently experiencing a 3 to 4 sec delay in call setup. Every time an extension on the PBX side dials an IP extension, it takes about 3 sec before we hear a ring tone.
I checked the debug on the Cisco side, and according to the time stamps, there is a difference of 3 sec between the fist digit of the called party and the last digit of the caller ID. Moreover, there is approximately a 100ms delay from the time the Cisco router send an acknowledgment and receiving the next digit from the PBX!!
Is there a way to speed up this process? What are the parameters that can be changed in order to affect this setup time?
Any idea, help will be appreciated.
I pasted a small copy of the debug:
