I am trying to connect a Pantel VoIP door phone (one-button model) to my UC520 that is currently in production. I have followed some other posts here to modify config to allow for SIP to SIP communication. However, 2 things still bother me; 1. Door phone has an IP on the data network - If I try to statically assign an IP from the voice network, I lose connectivity. Stupid quesiton, but door phone needs to have an IP on my voice network, correct? 2. Phone registers with UC520. Tested yields a busy signal when the button is pressed. Below is the config (modified for SIP use) that is currently in place. Can anyone shed some light on this issue? Thanks, Paul- voice service voip |

Update
I did more shooting in the dark and added the following:
UC520LA01#config t
UC520LA01(config)#sip
UC520LA01(config-sip-ua)#credentials username pancode password 654321 realm 10.1.1.1
Customer now able to place calls from door phone to internal extension; however, when fully tested with door lock, it appears that the tone for the key pressed (8 in our case) does not get back to the door phone to release the lock. I've modified the DTMF signaling to transparent, but have not tested yet.
Has anyone configured signaling from a SCCP phone back to a SIP phone successfully?
Thanks,
Paul-
