SCCP to MGCP calls

Answered Question

We have a VG224 configured for MGCP and used for faxes. Our IP and analog phones are SCCP. We cannot call SCCP to MGCP, but can call MGCP (using a butt set off of the 66A block). Our partitions/CSSs are good. We can call MGCP to MGCP. Everything is G711. Is there some service or enterprise parameter that may not allow for these calls? Any ideas?

I have this problem too.

If you're on 12.4(20)T watch out for this bug: CSCsr87229

You can try changing the caller ID or doing a 'debug mgcp packet' to see if you see the unsupported caller ID length
