I have a CME with several cisco phones and 1 SIP TSP. SIP trunk is registered and calls are coming in and out, but the thing is that only 1 active call can be made. If one is active second call cannot be made. I contacted our TSP, they have asterisk on their side and they said that if I want to use more channels I have make more registers with different usernames. Router model is 2900 with universal IOS 15.2. this is the old config of sip-ua :
sip-ua
credentials username xxxxxxxxxxx password 7 0xxxxxxxxxxxxxxxxx realm xxxxxxxxxxxxxxxx
authentication username xxxxxxxxxxxxxxxxx password 7 xxxxxxxxxxxxxxxxxxxxxx
no remote-party-id
max-forwards 15
registrar ipv4:xxxxxxxxxxxxx expires 600
host-registrar
and this is the new one:
sip-ua
credentials username xxxxxxxxxxxx password 7 xxxxxxxxxxxxxxxxx realm xxxxxxxxxxxxx
credentials username xxxxxxxxxxxx password 7 xxxxxxxxxxxxxxxxx realm xxxxxxxxxxxxx
authentication username xxxxxxxxxx password 7 xxxxxxxxxxxxxxxxx
no remote-party-id
max-forwards 15
registrar 1 ipv4:xxxxxxxxxxxxx expires 600
registrar 2 ipv4:xxxxxxxxxxxxx expires 600
host-registrar
actually the realms and registar-s are the same IP addresses, passwords are also the same, only difference is in username. The thing is that I cannot enter new authentiation parameters, when I enter the new one it replaces the old one.
and this is the register status :
show sip-ua register status
--------------------- Registrar-Index 1 ---------------------
Line peer expires(sec) registered P-Associ-URI
================================ ========== ============ ========== ============
9954932203300 20002 64 yes
9954932203301 -1 64 no
--------------------- Registrar-Index 2 ---------------------
Line peer expires(sec) registered P-Associ-URI
================================ ========== ============ ========== ============
9954932203300 20002 68 yes
9954932203301 -1 68 no
as you can see second username cannot register.
So I have 2 questions:
1) Does cisco router's SIP trunk support more than one channels ( simultineous calls) or not?
2) If it doesnot support , how can I add second register and what is needed to use it for several calls at a time?
