[cisco-voip] router to router (SCCP/h323 to SIP) calls don't work in SRST

[Lelio Fulgenzi]

ya know, I think I just answered my own question after sending this off.... 

i'm guessing I need a more specific dial-peer on the far end router which more closely matches the dial-peer on local router. 

so, something like this? the question is, can i use the router address or should i use the CUE ip address? 

hmmm, something to try later 



R outer A:

Does anyone know if there is anything special you have to do to make calls from an SCCP phone on one SRST router to a SIP endpoint on another SRST router work? 

Here's what I have and can do: 

    • two routers in SRST mode 
    • all phones register properly, some to one router, some to another 
    • I can make a call from phone A on router A to phone B on router B (and vice versa) 
    • I can make a call from phone A on router A to Unity Express A on router A and be transferred to phone B on router B 

I can NOT place a call from phone A on router A to Unity Express B on router B. 

I'm pretty sure Router B is getting the call, because a "debug voice dialpeer all" started spewing out stuff on Router B like it was going out of style. It even showed matches. I can post the full debug next week, but just thought there would be a quick(?) answer. 

I think these are the relevant configs, but will post more if needed:
