Hello everyone, I hope maybe someone can help me out.
I have a cordless phone connected to my 3725 on FXS port 1/1/1.
System image file is "slot0:c3725-adventerprisek9-mz.124-12.bin"

PROBLEM: I call my cordless from my cell. Cellphone can hear voice, but callee on the cordless phone can not hear anything.

What could be the problem here?

    On 2811 seems to work fine. Waiting for additional memory for 3725 to see if an IOS upgrade solves these problems.

    Just looking at this makes my head hurt and makes me afraid to even start CCNA Voice lol

    Heh. I know. I welcome the challenge, and honestly Voice a lot of fun because you get to directly see [hear] the product of your work! Ringing phones! Also keep in mind I have a lot of stuff in this config that is probably NOT on the CCNA voice, mostly SIP trunk stuff. I'm just starting CCNA Voice but so far I have heard no mention of SIP trunking.
