We have a client who wants to integrate Cisco IP Telephony with Old Ericsson PBX MD110 BC9. The scenario is as follows:
Cisco IP Telephony (New Building):
1- Cisco Voice Gateways 2921
2- Cisco 7816 CM 8.6 Servers
3- Cisco 7825 Unity 8.X Servers
4- Total Extensions = 300
Ericsson Analog Telephony (Old Building)
1- Ericsson MD110 BC9
2- Total Extensions = 1000
3- Total Outside Lines = 250
For integration we have proposed the following:
1- Cisco 2921 with VWIC2-1MFT-T1/E1
2- Ericsson TLU76/11 E1 Card
Integrating VWIC2-1MFT-T1/E1 using QSIG with TLU76/11 E1 Card.
1- Is this solution correct? (Can we integrate these two using QSIG with Comm. Manager 8.6)
2- What type of configuration & IOS is required?
2- Is it possible to integrate them using Analog Lines i.e. FXO, FXS or E/M? If Yes, what type of card is best suited.
