Unity drops call to Cisco ITS (IOS telephony service) router
2620 64/16; tried both 2600-is3x-mz.123-1 and c2600-is3x-mz.122-15.T5
initial problem: dtmf relay not working correctly between ITS router and unity; could call in and reach unity via ITS router but unity no respond to entered digits. proved this to be issue by inserting a second 2620 as pstn router and creating voip dial peer with dtmf-relay to ITS router and wah-lah unity responds to digits.
current problem: while in unity auto attendant and upon entering an ip phone extension, the call just drops. have seen this before with ccm due to calling search space issues, but doesn't apply in ITS config scenario.
can call from one ip phone extension to another via unity auto attendant with no problems; problem only occurs when caller entering ip phone extension in unity is coming from the voip dial peer.
any help or advice greatly appreciated. would like resolve not only this dropping call scenario but also dtmf issue if anyone has a workaround. in earlier post someone suggested an ios downgrade but the recommended version doesnt seem to be available for 2620 with 64/16.
