User experiences a delay in call initiation when making local calls

Core Issue

Cisco CallManager uses an interdigit timer to allow users sufficient time to enter the digits required to place their call.

Resolution

For Cisco CallManagers in North America making use of the @ macro in their route patterns, the simplest solution is to use a route filter.

To resolve this issue, modify the default seven digit route filter.

Perform these steps:

  1. Make sure the local area code does not exist.
  2. Make sure the end of dialing does not exist.

If you are not making use of the @ macro in your dialing plan, you can shorten the interdigit timer value by referring to Delay in Call Establishment: Configuring the Interdigit Timeout.

If the delay is observed for on-net calls (such as calls between IP phones within a Cisco CallManager cluster), refer to User experiences a delay in call initiation when making local calls.

For more information, refer to Cisco 7900 Series IP Phones: Q&A.
