We have a CCM Setup with 4 digits extensions which we converted to 5-digits extentions due to customer requirement. The customer also wanted the 4-digit and 5-digit extention co-existentfor some time, so that the callers calling 4-digit can also reach new 5-digits extentions.Voice Gateways use MGCP.
Following steps were followed:
1.Modified existing translation rule to convert incoming calls look for 5 digits IP Phones extn(instead of earlier 4-digits).
2.Added translation rule to convert 4-digit extentions to 5-digits for people dialing internally(in case caller still dials 4-digit extension).
3.Already converted all existing IP Phone 4-digit extentions to 5-digits.
Now we get a delay on dialing 4-gits extentions(as I believe the CCM waits for interdigit timeout), unlike earlier when there was no delay.
Can somebody suggest to get RID of this delay, with both 4 & 5 digit extension co-existing.
