I have 2 Cisco MCS7816 - CUCM Cluster with both nodes running UCM 7.1(2a).
There's also a 2811 (IOS 12.4(24)T) configured as H.323 Gateway for the UCM cluster. Can't be MGCP because in this area the telco's device only supports R2 signalling. This router has a VWIC2-2MFT-T1/E1 connected to PSTN through E1.
This router has also 2x VIC2-4FXO cards which will be connected to Cell lines but please ignore those voice-port 0/0/x configs as it's not being used yet.
Now the problems:
I have slip secs increasing no matter what clock settings I configure on the router. I spoke directly with the telco's guy who configures their side and he told me I should set my router to use external clock. Is "clock source line primary" the correct setting for the router to use external clock?
I also noticed that when I *receive* a call there's some noise on the line but if I place the call the quality is perfect.
Another problem is I don't get the caller IDs. This service is enabled on my E1 line, but I can't see the "calling number" on router debugs when a call is placed from PSTN so when the call gets to the end device it just shows "unknown number".
Any tips on this?
Router configs are attached.
Thanks in advice.
