Router A and Router B are 2611XM's. Router A is running CME and has 5 IP Phones. Both routers have FXO ports connected the local PSTN at their respective locations.
Call Transfer will work under the following conditions:
1. 1st IP phone calls up a 2nd IP phone. 2nd IP phone can transfer to a 3rd IP phone.
2. Router A (FXO) receives a call and is PLARed to an IP phone. This call can be transferred to a 2nd IP phone.
Call Transfer does NOT work under the following condition:
1. Router B (FXO) receives a call. This call is PLARed to an IP phone on Router A. When the transfer button is pressed, the calling party hears MOH. But as soon as the last digit is dialed (DN of the 2nd IP phone), the call gets disconnected and the 1st IP phone display is reverted back to idle.
I've already configured codec g711ulaw on both VoIP dial-peers with no help. (it was g729 but MOH wasn't working)
