Anyone know how to dial other numbers on the same SIP providers network from the UC320?
The SIP "phone number" on the UC320 is 844 xxx xxx with Voiptalk
I have a VoIP client on my iPhone also registered with Voiptalk of 844 yyy yyy
I can dial the UC320 from my iPhone by dialling 844 xxx xxx - the call is placed entirely over Voiptalk's network and is free.
But if i try to dial 844 yyy yyy from the UC320 it dials a local six digit number over the SIP trunk instead of the 9 digit Voiptalk number.
I also have a Cisco WIP310 which is registered on the Voiptalk network with 844 zzz zzz and I can dial either the iPhone or the UC320 over the Voiptalk network but again if i dial 844 zzz zzz from the UC320 it dials a local regular phone number 844zzz instead of the Voiptalk number. All the calls are placed over the SIP trunk but it would be great if the UC320 could dial other numbers on the voiptalk network because these calls would be free regardless of where the iPhone or the WIP310 were provided they are connected to the internet.
