max. of 15 digits on ISDN callback

Hello,

on an c3620 with 12.2(7) IP we have the problem on callback, that there is an limitation of 15 digits on the calling ISDN number. Have you ever heard about that problem? Which IOS version will fix it?

Re: max. of 15 digits on ISDN callback

Duplicate question?

The restriction is due to the ITU spec E.164, section 4.5 (The maximum number length shall be 15 digits).
