Hi,
we have the following scenario:
- Remote site
CME 10.5
SIP phones / SCCP phones
- Main Office
CUCM 11.5
SIP phones / SCCP phones
- Remote office connect to Main office by VPN
- In the Main office there was a CME but was replace by the current CUCM 11.5 last weekend.
- With CME in main office there was no problem, but after the installation of CUCM this issue was detected.
The calls from remote site with SCCP phones to Main Office work fine and from Main office to remote side also.
The calls from remote site with SIP phones to Main Office cannot be completed but calls from main office to remote site with SIP phones work well.
Currently this is the dial-peer set in remote office (CME).With this we can dial from remote site to main office just with SCCP phones.
dial-peer voice 198 voip
description *** to Main office ****
destination-pattern 15..
session target ipv4:X.X.X.X (CUCM)
voice-class codec 1
dtmf-relay h245-alphanumeric
We also tried with SIP option but for this case did not work for SCCP and SIP phones
